date: enable FEATURE_DATE_NANO

Provide a WIN32 implementation of clock_gettime(2), though only
with support for CLOCK_REALTIME.  This makes it possible to enable
FEATURE_DATE_NANO which adds support for the %N date format.

MinGW-w64 has clock_gettime(2) but it's in the winpthreads library
and we don't want to bother with that.
