declares these things.
To do that goto the widget where you get a failure message and add a new
dependency to a new UI script where you copy/paste the code from

// returns a date object you can test against for date/time
new Date(getDateFromFormat(newValue, g_user_date_time_format));
// returns a date object you can test against for date
new Date(getDateFromFormat(newValue, g_user_date_format));
