  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

This function parses and reformats time (hours and minutes) casually entered into a text field so that it can be converted to a valid time by Filemaker. It also includes tests so that, if an invalid time string is entered, it will return an error message instead of an invalid time. Further, it incorporates code from the TimeMask custom function written by Steve Gerow of Abrazos Data Consulting that logically assigns AM or PM to times entered without that data between 7am and 7pm. Many thanks to Steve, and to Brian Dunning.

Adding the following as the first Case element at the end allows an empty time entry to pass FMP validation when this function returns its result directly into a FMP time field.

Case ( isempty ( nums ) , "" , //Return the empty field so validation works.


This is a great custom function!

Remove the first line of this, "ParseTime ( timeText )" from the calculation body.
