/**
* eTemplate date widget
*
* Deals with date and time. Overridden to handle date-houronly as a transform
*
* Supported attributes: dataformat[,mode]
* dataformat: '' = timestamps or automatic conversation, or eg. 'Y-m-d H:i:s' for 2002-12-31 23:59:59
* mode: &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
* &64 = prefix r/o display with weeknumber and dow
* &128 = no icon to trigger popup, click into input trigers it, also removing the separators to save space
*
* @todo validation of date-duration
*
* @info Communication between client and server is always done as a string in ISO8601/W3C
* format ("Y-m-d\TH:i:sP"). If the application specifies a different format
* for the field, the conversion is done as needed understand what the application
* sends, and to give the application what it wants when the form is submitted.
