*: use long long to print time_t

Since we can't assume time_t to be long, int, or even long long, this
consistently uses %lld/long long (or %llu/unsigned long long in a few
cases) to print time_t/susecond_t values.  This should fix a bunch of
warnings, on NetBSD in particular.

(Unfortunately, there seems to be no "PRId64" style printing macro for
time_t...)
