@abstract widget that reads a date and/or time
@param Options/$cell['size'] = $format[,$options],
@param $format: ''=timestamp or eg. 'Y-m-d H:i' for 2002-12-31 23:59
@param $options: &1 = year is int-input not selectbox, &2 = show a [Today] button, \
&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
@discussion This widget is independent of the UI as it only uses etemplate-widgets and has therefor no render-function
