Oh, the "2^31 seconds are enough time for everybody",
brought to you by one or more careless UNIX designers
who might be lucky enough to be alive and 100+ years
old when this bug actually manifests.
In GNU/Linux, time_t is typedef'ed from __time_t, that
is typedef'ed from __TIME_T, that in turn typedef'ed
from __SLONGWORD_TYPE, that is defined from 'long int'.
Even today 64 bit architectures define 'long int' as
64 bit on some cases. Hopefully most 32-bit architectures
will perish until 2038. Nowadays, AMD64 slowly becomes
commodoty hardware, so I'm optimistic.
