I can't mind-read the intention of the change, but the effect
is to do unsigned div/mod instead of signed.  This allows the
time value to be treated as an unsigned 32-bit number, so we
should be looking at a 2106 problem not a 2038 problem.

Unfortunately while gmtime() is right, asctime() is getting
its centuries in a twist:
