pascal void GetDateTime(unsigned long *secs); 

You're passing it a long when you should be using an unsigned long -
since the toolbox uses some day in 1904 (WHY do they do this?  It
seems REALLY gratuitous to go that far back), it's already wrapped
past the maximum positive integer that can represented with a long -
you must use an unsigned long.
