* eTemplate extension to input or display date and/or time values
|
|
*
|
|
* Contains the following widgets: Date, Date+Time, Time, Hour, Duration
|
|
*
|
|
* Supported attributes: format[,options]
|
|
* format: ''=timestamp, or eg. 'Y-m-d H:i' for 2002-12-31 23:59
|
|
* options: &1 = year is int-input not selectbox, &2 = show a [Today] button, (html-UI always uses jscal and dont care for &1+&2)
|
|
* &4 = 1min steps for time (default is 5min, with fallback to 1min if value is not in 5min-steps),
|
|
* &8 = dont show time for readonly and type date-time if time is 0:00,
|
|
* &16 = prefix r/o display with dow
|
|
* &32 = prefix r/o display with week-number
|
|
*
|
|
* This widget is independent of the UI as it only uses etemplate-widgets and has therefor no render-function.
|
|
* Uses the adodb datelibary to overcome the windows-limitation to not allow dates before 1970
