/**
 * 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
