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

Formats a timestamp according to a format string, replacing date/time component placeholders with respective data. See the Substitute command in the function to determine (or change) the placeholders to use. Includes placeholders to allow upper/lower case for text components (eg, day names).
Use a null input timestamp ("") to format the current date/time.

hr12 = Mod ( h - 1; 12 ) + 1
should be
hr12 = Mod ( hr - 1; 12 ) + 1

["[am]"; If ( h < 12; "am"; "pm" )];
should be
["[am]"; If ( hr < 12; "am"; "pm" )];

Watch out for when keying in the formatting parameters. The case of the parameter often controls the case of the output e.g. "[month]" vs "[MONTH]".

Here's an exception: The parameter "[mm]" generates minutes while the parameter "[MM]" generates months.
