Can someone tell me how to use function now() or today() in Build or Xfrom,
in order to record the date/time at the data collection?
1st: there are properties that you can use to set the start (first begun)
and end times (marked-as-finalized) of a form.
and on http://xlsform.org/ search for "Metadata" in XLSForms, these are
added to the settings page.
not sure how to use these within Build.
2nd: if you need to record a date and not allow it to be revised later when
you edit or swipe-through a form (or any calculation that you don't want to
be updated after its first time), you can wrap it in the once() function.
If your calculate expression is:
then only if the field is empty will once() execute the calculation that it
wraps and store the resulting value in the field.
