Looks like seconds since the Epoch (Jan 1, 1970). Except for the
100 and 400 year exceptions and leap year tallying, it's just the
simple conversion of years, months, days, hours and minutes to
seconds since the Epoch time.
Here's the BSD man page for the asctime, ctime, difftime, gmtime,
localtime, mktime functions:
