in reply to getting answer 70 years off

From the documentation for Time::Local in CPAN:

This module provides functions that are the inverse of built-in perl functions localtime() and gmtime(). They accept a date as a six-element array, and return the corresponding time(2) value in seconds since the system epoch (Midnight, January 1, 1970 GMT on Unix, for example).

The difference between system epoch start (1970) and the localtime conversion point (1900) appears to account for your missing 70 years.

    IIRC, Mac OS set the epoch at Jan 1, 1900 for some reason.

    It helps to remember that the primary goal is to drain the swamp even when you are hip-deep in alligators.
