Subject: [PATCH] tests: Handle various time_t sizes in printf

The members of the timeval struct are both signed (defined by POSIX)
and typically both 64 bits on a system where time_t is 64 bits.  This
is possible also on 32 bit systems where time_t is larger to handle
the 2038 problem.

It's practically impossible to find a type and printf format that
works even on all glibc systems.  Play it safe and always use printf
with intmax_t.
