You didn't mention how your Applesoft program was getting the time,
but I'm guessing that it's PEEKing it from the locations in the
ProDOS global page.

ProDOS only updates this location when a ProDOS file operation is
executed.  If you do a PRINT CHR$(4)"verify" command, ProDos will
update the global page time and date.
