Cast time_t to long long in order to print it.
time_t is only specified as an integer type per POSIX. To reliably
print it, better cast it to "long long", which is at least 64 bits wide
and can represent values beyond 2038.
Printing as a "long" could cause problems on ILP32 systems using a 64
bits time_t (eg OpenBSD/armv7).
