This isn't the 32/64 bit issue. This is the 31/32 bit issue.

An OS with a 32-bit time_t has a choice. With the "negative" values
of a 32-bit integer, it can represent 1901-1969 or 2038-2106: pick
one. I take it Linux chose to handle 2038-2106, and you don't like
that choice.

I think POSIX says it's supposed to be unsigned, so arguably
Linux is right and the BSDs are wrong as far as standards compliance.
