Hi all,
Second of three questions coming up today...I think...
If our collectors don't have network access in the field, how/when does the
form tag with metadata like date, time if we used the automatic functions
in the form ('start', 'end', 'today' etc). Will the date/time read as when
collected, when the device returns to network, or when uploaded to the
server?
Thanks!
Jordan
The preload parameters are determined relative to certain actions on the
form:
start - a blank form is opened (creating a new submission instance)
end - the form is marked-as-finalized.
today() is a function. Each time you open the form, today() is
re-calculated. If you want to remember today() from some given day, you
should wrap it in once() to prevent it being re-calculated.

Jordan,
To add to what Mitch said, the time comes from the device time (and
not network or GPS time). Device time isn't guaranteed to be the
actual time (e.g., network time can be wrong, dead battery on device
can reset time), so plan accordingly.
