 *
 *  The Any+Time(TM) JavaScript Library provides the following ECMAScript
 *  functionality:
 *
 *    AnyTime.Converter
 *      Converts Dates to/from Strings, allowing a wide range of formats
 *      closely matching those provided by the MySQL DATE_FORMAT() function,
 *      with some noteworthy enhancements.
 *
 *    AnyTime.pad()
 *      Pads a value with a specific number of leading zeroes.
 *      
 *    AnyTime.noPicker()
 *      Destroys a calendar widget previously added by AnyTime.picker().
 *      Can also be invoked via jQuery using $(selector).AnyTime_noPicker()
 *
 *    AnyTime.picker()
 *      Attaches a calendar widget to a text field for selecting date/time
 *      values with fewer mouse movements than most similar pickers.  Any
 *      format supported by AnyTime.Converter can be used for the text field.
 *      If JavaScript is disabled, the text field remains editable without
 *      any of the picker features.
 *      Can also be invoked via jQuery using $(selector).AnyTime_picker()
 *
 *  IMPORTANT NOTICE:  This code depends upon the jQuery JavaScript Library
 *  (www.jquery.com), currently version 1.4.
 *
 *  The Any+Time(TM) code and styles in anytime.css have been tested (but not
 *  extensively) on Windows Vista in Internet Explorer 8.0, Firefox 3.0, Opera
 *  10.10 and Safari 4.0.  Minor variations in IE6+7 are to be expected, due
 *  to their broken box model. Please report any other problems to the author

//  AnyTime.Converter
//
//  This object converts between Date objects and Strings.
//
//  To use AnyTime.Converter, simply create an instance for a format string,
//  and then (repeatedly) invoke the format() and/or parse() methods to
//  perform the conversions.  For example:
//
//    var converter = new AnyTime.Converter({format:'%Y-%m-%d'})
//    var datetime = converter.parse('1967-07-30') // July 30, 1967 @ 00:00
//    alert( converter.format(datetime) ); // outputs: 1967-07-30
//
//  Constructor parameter:
//
//  options - an object of optional parameters that override default behaviors.
//    The supported options are:
//
//    baseYear - the number to add to two-digit years if the %y format
//      specifier is used.  By default, AnyTime.Converter follows the
//      MySQL assumption that two-digit years are in the range 1970 to 2069
//      (see http://dev.mysql.com/doc/refman/5.1/en/y2k-issues.html).
//      The most common alternatives for baseYear are 1900 and 2000.
//
//    dayAbbreviations - an array of seven strings, indexed 0-6, to be used
//      as ABBREVIATED day names.  If not specified, the following are used:
//      ['Sun','Mon','Tue','Wed','Thu','Fri','Sat']
//      Note that if the firstDOW option is passed to AnyTime.picker() (see
//      AnyTime.picker()), this array should nonetheless begin with the 
//      desired abbreviation for Sunday.
//
//    dayNames - an array of seven strings, indexed 0-6, to be used as
//      day names.  If not specified, the following are used: ['Sunday',
//        'Monday','Tuesday','Wednesday','Thursday','Friday','Saturday']
//      Note that if the firstDOW option is passed to AnyTime.picker() (see
//      AnyTime.picker()), this array should nonetheless begin with the
//      desired name for Sunday.
//
//    eraAbbreviations - an array of two strings, indexed 0-1, to be used
//      as ABBREVIATED era names.  Item #0 is the abbreviation for "Before
//      Common Era" (years before 0001, sometimes represented as negative
//      years or "B.C"), while item #1 is the abbreviation for "Common Era"
//      (years from 0001 to present, usually represented as unsigned years
//      or years "A.D.").  If not specified, the following are used:
//      ['BCE','CE']
//
//    format - a string specifying the pattern of strings involved in the
//      conversion.  The parse() method can take a string in this format and
//      convert it to a Date, and the format() method can take a Date object
//      and convert it to a string matching the format.
//
//      Fields in the format string must match those for the DATE_FORMAT()
//      function in MySQL, as defined here:
//      http://tinyurl.com/bwd45#function_date-format
//
//      IMPORTANT:  Some MySQL specifiers are not supported (especially
//      those involving day-of-the-year, week-of-the-year) or approximated.
//      See the code for exact behavior.
//
//      In addition to the MySQL format specifiers, the following custom
//      specifiers are also supported:
//
//        %B - If the year is before 0001, then the "Before Common Era"
//          abbreviation (usually BCE or the obsolete BC) will go here.
//
//        %C - If the year is 0001 or later, then the "Common Era"
//          abbreviation (usually CE or the obsolete AD) will go here.
//
//        %E - If the year is before 0001, then the "Before Common Era"
//          abbreviation (usually BCE or the obsolete BC) will go here.
//          Otherwise, the "Common Era" abbreviation (usually CE or the
//          obsolete AD) will go here.
//
//        %Z - The current four-digit year, without any sign.  This is
//          commonly used with years that might be before (or after) 0001,
//          when the %E (or %B and %C) specifier is used instead of a sign.
//          For example, 45 BCE is represented "0045".  By comparison, in
//          the "%Y" format, 45 BCE is represented "-0045".
//
//        %z - The current year, without any sign, using only the necessary
//          number of digits.  This if the year is commonly used with years
//          that might be before (or after) 0001, when the %E (or %B and %C)
//          specifier is used instead of a sign.  For example, the year
//          45 BCE is represented as "45", and the year 312 CE as "312".
//
//        %# - the timezone offset, with a sign, in minutes.
//
//        %+ - the timezone offset, with a sign, in hours and minutes, in
//          four-digit, 24-hour format with no delimiter (for example, +0530).
//          To remember the difference between %+ and %-, it might be helpful
//          to remember that %+ might have more characters than %-.
//
//        %: - the timezone offset, with a sign, in hours and minutes, in
//          four-digit, 24-hour format with a colon delimiter (for example,
//          +05:30).  This is similar to the %z format used by Java.  
//          To remember the difference between %: and %;, it might be helpful
//          to remember that a colon (:) has a period (.) on the bottom and
//          a semicolon (;) has a comma (,), and in English sentence structure,
//          a period represents a more significant stop than a comma, and
//          %: might be a longer string than %; (I know it's a stretch, but
//          it's easier than looking it up every time)!
//  	
//        %- - the timezone offset, with a sign, in hours and minutes, in
//          three-or-four-digit, 24-hour format with no delimiter (for
//          example, +530).
//
//        %; - the timezone offset, with a sign, in hours and minutes, in
//          three-or-four-digit, 24-hour format with a colon delimiter
//          (for example, +5:30).
//
//        %@ - the timezone offset label.  By default, this will be the
//          string "UTC" followed by the offset, with a sign, in hours and  
//          minutes, in four-digit, 24-hour format with a colon delimiter
//          (for example, UTC+05:30).  However, if Any+Time(TM) has been
//          extended with a member named utcLabel (for example, by the
//          anytimetz.js file), then it is assumed to be an array of arrays,
//          where the primary array is indexed by time zone offsets, and
//          each sub-array contains a potential label for that offset.
//          When parsing with %@, the array is scanned for matches to the
//          input string, and if a match is found, the corresponding UTC
//          offset is used.  When formatting, the array is scanned for a
//          matching offset, and if one is found, the first member of the
//          sub-array is used for output (unless overridden with
//          utcFormatOffsetSubIndex or setUtcFormatOffsetSubIndex()).
//          If the array does not exist, or does not contain a sub-array
//          for the offset, then the default format is used.
//
//    monthAbbreviations - an array of twelve strings, indexed 0-6, to be
//      used as ABBREVIATED month names.  If not specified, the following
//      are used: ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep',
//        'Oct','Nov','Dec']
//
//    monthNames - an array of twelve strings, indexed 0-6, to be used as
//      month names.  If not specified, the following are used:
//      ['January','February','March','April','May','June','July',
//        'August','September','October','November','December']
//
//    utcFormatOffsetAlleged - the offset from UTC, in minutes, to claim that
//      a Date object represents during formatting, even though it is formatted
//      using local time. Unlike utcFormatOffsetImposed, which actually
//      converts the Date object to the specified different time zone, this
//      option merely reports the alleged offset when a timezone specifier
//      (%#, %+, %-, %:, %; %@) is encountered in the format string.
//      This primarily exists so AnyTime.picker can edit the time as specified
//      (without conversion to local time) and then convert the edited time to
//      a different time zone (as selected using the picker).  Any initial
//      value specified here can be changed by setUtcFormatOffsetAlleged().
//      If a format offset is alleged, one cannot also be imposed (the imposed
//      offset is ignored).
//
//    utcFormatOffsetImposed - the offset from UTC, in minutes, to specify when
//      formatting a Date object.  By default, a Date is always formatted
//      using the local time zone.
//
//    utcFormatOffsetSubIndex - when extending AnyTime with a utcLabel array
//      (for example, by the anytimetz.js file), the specified sub-index is
//      used to choose the Time Zone label for the UTC offset when formatting
//      a Date object.  This primarily exists so AnyTime.picker can specify
//      the label selected using the picker.  Any initial value specified here
//      can be changed by setUtcFormatOffsetSubIndex().
//
//    utcParseOffsetAssumed - the offset from UTC, in minutes, to assume when
//      parsing a String object.  By default, a Date is always parsed using the
//      local time zone, unless the format string includes a timezone
//      specifier (%#, %+, %-, %:, %; or %@), in which case the timezone
//      specified in the string is used. The Date object created by parsing
//      always represents local time regardless of the input time zone.
//
//    utcParseOffsetCapture - if true, any parsed string is always treated as
//      though it represents local time, and any offset specified by the string
//      (or utcParseOffsetAssume) is captured for return by the 
//      getUtcParseOffsetCaptured() method.  If the %@ format specifier is
//      used, the sub-index of any matched label is also captured for return
//      by the getUtcParseOffsetSubIndex() method.  This primarily exists so
//      AnyTime.picker can edit the time as specified (without conversion to
//      local time) and then convert the edited time to a different time zone
//      (as selected using the picker).

};

//=============================================================================
//  AnyTime.picker()
//
//  Creates a date/time entry picker attached to a specified text field.
//  Instead of entering a date and/or time into the text field, the user
//  selects legal combinations using the picker, and the field is auto-
//  matically populated.  The picker can be incorporated into the page
//	"inline", or used as a "popup" that appears when the text field is
//  clicked and disappears when the picker is dismissed. Ajax can be used
//  to send the selected value to a server to approve or veto it.
//
//  To create a picker, simply include the necessary files in an HTML page
//  and call the function for each date/time input field.  The following
//  example creates a popup picker for field "foo" using the default
//  format, and a second date-only (no time) inline (always-visible)
//  Ajax-enabled picker for field "bar":
//
//    <link rel="stylesheet" type="text/css" href="anytime.css" />
//    <script type="text/javascript" src="jquery.js"></script>
//    <script type="text/javascript" src="anytime.js"></script>
//    <input type="text" id="foo" tabindex="1" value="1967-07-30 23:45" />
//    <input type="text" id="bar" tabindex="2" value="01/06/90" />
//    <script type="text/javascript">
//      AnyTime.picker( "foo" );
//      AnyTime.picker( "bar", { placement:"inline", format: "%m/%d/%y",
//								ajaxOptions { url: "/some/server/page/" } } );
//    </script>
//
//  The appearance of the picker can be extensively modified using CSS styles.
//  A default appearance can be achieved by the "anytime.css" stylesheet that
//  accompanies this script.  The default style looks better in browsers other
//  than Internet Explorer (before IE8) because older versions of IE do not
//  properly implement the CSS box model standard; however, it is passable in
//  Internet Explorer as well.
//
//  Method parameters:
//
//  id - the "id" attribute of the textfield to associate with the
//    AnyTime.picker object.  The AnyTime.picker will attach itself
//    to the textfield and manage its value.
//
//  options - an object (associative array) of optional parameters that
//    override default behaviors.  The supported options are:
//
//    ajaxOptions - options passed to jQuery's $.ajax() method whenever
//      the user dismisses a popup picker or selects a value in an inline
//      picker.  The input's name (or ID) and value are passed to the
//      server (appended to ajaxOptions.data, if present), and the
//      "success" handler sets the input's value to the responseText.
//      Therefore, the text returned by the server must be valid for the
//      input'sdate/time format, and the server can approve or veto the
//      value chosen by the user. For more information, see:
//      http://docs.jquery.com/Ajax.
//      If ajaxOptions.success is specified, it is used instead of the
//      default "success" behavior.
//
//    askEra - if true, buttons to select the era are shown on the year
//        selector popup, even if format specifier does not include the
//        era.  If false, buttons to select the era are NOT shown, even
//        if the format specifier includes ther era.  Normally, era buttons
//        are only shown if the format string specifies the era.
//
//    askSecond - if false, buttons for number-of-seconds are not shown
//        even if the format includes seconds.  Normally, the buttons
//        are shown if the format string includes seconds.
//
//    earliest - String or Date object representing the earliest date/time
//        that a user can select.  For best results if the field is only
//        used to specify a date, be sure to set the time to 00:00:00.
//        If a String is used, it will be parsed according to the picker's
//        format (see AnyTime.Converter.format()).
//
//    firstDOW - a value from 0 (Sunday) to 6 (Saturday) stating which
//      day should appear at the beginning of the week.  The default is 0
//      (Sunday).  The most common substitution is 1 (Monday).  Note that
//      if custom arrays are specified for AnyTime.Converter's dayAbbreviations
//      and/or dayNames options, they should nonetheless begin with the
//      value for Sunday.
//
//    hideInput - if true, the <input> is "hidden" (the picker appears in 
//      its place). This actually sets the border, height, margin, padding
//      and width of the field as small as possivle, so it can still get focus.
//      If you try to hide the field using traditional techniques (such as
//      setting "display:none"), the picker will not behave correctly.
//
//    labelDayOfMonth - the label for the day-of-month "buttons".
//      Can be any HTML!  If not specified, "Day of Month" is assumed.
//
//    labelDismiss - the label for the dismiss "button" (if placement is
//      "popup"). Can be any HTML!  If not specified, "X" is assumed.
//
//    labelHour - the label for the hour "buttons".
//      Can be any HTML!  If not specified, "Hour" is assumed.
//
//    labelMinute - the label for the minute "buttons".
//      Can be any HTML!  If not specified, "Minute" is assumed.
//
//    labelMonth - the label for the month "buttons".
//      Can be any HTML!  If not specified, "Month" is assumed.
//
//    labelTimeZone - the label for the UTC offset (timezone) "buttons".
//      Can be any HTML!  If not specified, "Time Zone" is assumed.
//
//    labelSecond - the label for the second "buttons".
//      Can be any HTML!  If not specified, "Second" is assumed.
//      This option is ignored if askSecond is false!
//
//    labelTitle - the label for the "title bar".  Can be any HTML!
//      If not specified, then whichever of the following is most
//      appropriate is used:  "Select a Date and Time", "Select a Date"
//      or "Select a Time", or no label if only one field is present.
//
//    labelYear - the label for the year "buttons".
//      Can be any HTML!  If not specified, "Year" is assumed.
//
//    latest - String or Date object representing the latest date/time
//        that a user can select.  For best results if the field is only
//        used to specify a date, be sure to set the time to 23:59:59.
//        If a String is used, it will be parsed according to the picker's
//        format (see AnyTime.Converter.format()).
//
//    placement - One of the following strings:
//
//      "popup" = the picker appears above its <input> when the input
//        receives focus, and disappears when it is dismissed.  This is
//        the default behavior.
//
//      "inline" = the picker is placed immediately after the <input>
//        and remains visible at all times.  When choosing this placement,
//        it is best to make the <input> invisible and use only the
//        picker to select dates.  The <input> value can still be used
//        during form submission as it will always reflect the current
//        picker state.
//
//        WARNING: when using "inline" and XHTML and including a day-of-
//        the-month format field, the input may only appear where a <table>
//        element is permitted (for example, NOT within a <p> element).
//        This is because the picker uses a <table> element to arrange
//        the day-of-the-month (calendar) buttons.  Failure to follow this
//        advice may result in an "unknown error" in Internet Explorer.
//
//    The following additional options may be specified; see documentation
//    for AnyTime.Converter (above) for information about these options:
//
//      baseYear
//      dayAbbreviations
//      dayNames
//      eraAbbreviations
//      format
//      monthAbbreviations
//      monthNames
//
//  Other behavior, such as how to format the values on the display
//  and which "buttons" to include, is inferred from the format string.

		//
		//  * LeftArrow moves focus left, continued to previous week.
		//  * RightArrow moves focus right, continued to next week.
		//  * UpArrow moves focus to the same weekday in the previous week.
		//  * DownArrow moves focus to same weekday in the next week.
		//  * PageUp moves focus to same day in the previous month.
		//  * PageDown moves focus to same day in the next month.
		//  * Shift+Page Up moves focus to same day in the previous year.
		//  * Shift+Page Down moves focus to same day in the next year.
		//  * Home moves focus to the first day of the month.
		//  * End moves focus to the last day of the month.
		//  * Ctrl+Home moves focus to the first day of the year.
		//  * Ctrl+End moves focus to the last day of the year.
		//  * Esc closes a DatePicker that is opened as a Popup.  
		//
		//  The following actions (for multiple-date selection) are NOT
		//	supported:
		//  * Shift+Arrow performs continous selection.  
		//  * Ctrl+Space multiple selection of certain days.
		//
		//  The authoring practices do not specify behavior for a time picker,
		//  or for month-and-year pickers that do not have a day-of-the-month,
		//  but AnyTime.picker uses the following behavior to be as consistent
		//  as possible with the defined datepicker functionality:
		//  * LeftArrow moves focus left or up to previous value or field.
		//  * RightArrow moves focus right or down to next value or field.
		//  * UpArrow moves focus up or left to previous value or field.
		//  * DownArrow moves focus down or right to next value or field 
		//  * PageUp moves focus to the current value in the previous units
		//    (for example, from ten-minutes to hours or one-minutes to
		//	  ten-minutes or months to years).
		//  * PageDown moves focus to the current value in the next units
		//    (for example, from hours to ten-minutes or ten-minutes to 
		//    one-minutes or years to months).
		//  * Home moves the focus to the first unit button.
		//  * End moves the focus to the last unit button.
		//
		//  In addition, Tab and Shift+Tab move between units (including to/
		//	from the Day-of-Month table) and also in/out of the picker.
		//
		//  Because AnyTime.picker sets a value as soon as the button receives
		//  focus, SPACE and ENTER are not needed (the WAI-ARIA guidelines use
		//  them to select a value.
