It occurs to me that really early Unix used a time word in PDP-11 ticks,
not seconds.  So it ran out of time a lot sooner than 2038, like maybe
only a year after it started, at 60 ticks per second, 31.5 Megaseconds per
year.  This information was gleaned from a Mt.Xinu calendar from a few
years ago.
