High-precision date/time in C

> Time is a pair (seconds, nanoseconds),

I expect something diffferent, but isn't this just timespec_t[0] with different epoch? It's been in in POSIX since 2001.

The upside of timespec_t is it uses regular Unix epoch for seconds time, so thre is no need for things like "time_get_year", you use regular time_t APIs for that.
