==Requirements==

*Need widgets for selecting or entering dates and times
*Should support 12 or 24 hour clocks
*Should display times and dates in a localized manner

==Time Picker==

A widget for selecting times. It contains a textbox with a spinbuttons next to it. The textbox is actually three textboxes inside of a box styled to look like a textbox. The three textboxes allow entry of an hour, minute and second. The spinbuttons adjusts the value of the currently focused textbox. A fourth textbox appears for 12 hour clocks which allows selection of AM or PM.


<pre>
&lt;timepicker value="13:15"
            increment="10"
            hideseconds="false"/&gt;
</pre>

===Attributes===

; hideseconds : set to true to hide the seconds entry field.
; increment : the granularity of minutes that may be selected. For instance, 5 means that only minutes divisible by 5 may be selected. Pressing the spinbuttons while the minute field is focused will increment or decrement the minutes by this value.
; value : the default time to be set for the timepicker. The syntax is 'hh:mm:ss'.

===Constants===

; amIndicator: the label for AM
; hourLeadingZero: true if hours are displayed with a leading zero
; is24HourClock: boolean value indicating if a 24 hour clock is being used
; minuteLeadingZero: true if mintes are displayed with a leading zero
; pmIndicator: the label for PM
; secondLeadingZero: true if seconds are displayed with a leading zero

===Properties===

; dateValue : the current value selected in the timepicker as a Date object.
; disabled : the timepicker is disabled.
; hideSeconds : set to true to hide the seconds entry field.
; hour : the currently selected hour from 0 to 23.
; isPM : true if the hour is between 12 and 23.
; increment : gets and sets the value of the increment attribute.
; minute : the currently selected minute from 0 to 59.
; readOnly : the timepicker is read only and the user cannot modify the currently selected time.
; second : the currently selected second from 0 to 59.
; tabIndex : the tab order of the timepicker.
; value : the currently selected time in the form HH:MM:SS.

All of the properties above may be modified to change the current time.

===Events===

The change event is fired whenever the time is changed.

==Date Picker==

A widget for selecting dates. There are three varieties, chosen by setting the type attribute. The default datepicker, if no type attribute is present, is an entry datepicker. Other types are grid and popup.

*entry - contains a textbox with a spinbuttons next to it and works like the timepicker but for entering the year, month and date.
*grid - a calendar grid for selecting a date. The mouse may be used to click on a date or the keyboard may be used to navigate to a date.
*popup - a combination entry field with a dropdown button. Pressing the dropdrop button opens a popup with the grid in it.

<pre>
&lt;datepicker type="grid"
            firstdayofweek="0"
            value="Jul 20, 2005"
            hideyear="false"/&gt;
</pre>

===Attributes===

; firstdayofweek : which day of the week to display as the first day in the grid. The values range from 0 to 6, where 0 is Sunday. The default value is determined by the locale.
; hideyear : set to true to hide the year entry field. This would be used, for example, for birthday fields where the year is not always relevant.
; type : either grid or popup
; value : the default date to be set for the datepicker.

===Constants===
; dateLeadingZero: true if dates are displayed with a leading zero
; monthLeadingZero: true if months are displayed with a leading zero
; yearLeadingZero: true if years are displayed with leading zeroes

===Properties===

; date : the currently selected date from 1 to 31.
; dateValue : the current value selected in the datepicker as a Date object.
; disabled : the datepicker is disabled.
; month : the currently selected month from 0 to 11.
; open : true if the popup in a popup datepicker is open, or false otherwise. This property may be changed to open or close the popup. The open property is always false for entry and grid datepickers, and changing the value has no effect.
; readOnly : the datepicker is read only and the user cannot modify the currently selected date. However, in a grid or popup datepicker, the user may still navigate between the months.
; tabIndex : the tab order of the datepicker.
; value : the currently selected date in the form YYYY/MM/DD. Unlike, the month property, months in this value range from 01 to 12.
; year : the currently selected year from 1 to 9999.

All of the properties above may be modified to change the current date.

===Events===

The change event is fired whenever the date is changed.

The monthchange event is fired for the grid and popup datepickers whenever a new month is navigated to or displayed.
