Hi Jason,
parseDateTime converts a string to a date time. formatDateTime converts the Date and time value to a string.
When using the calendar, I assume your $DateOutput is an Attribute of type DateTime. Can you try formatDateTime($DateOutput, ‘HH:mm’ ) HH is 0-23 hh is 0-12 (see here) and the ‘a’ is returning the string am or pm.
Go make it
@marco not sure if this is the best way of doing it, but this is my Frankenstein solution, it works
