Clock: Consider return code on failed native clock_gettime(..) call; Add Win32 clock_gettime() implementation.
Consider return code on failed native clock_gettime(..) call
- Return Instant.EPOCH for all Instant variations (essentially 0)
- Return 0 for all 'long' variations (ms, ns)
Add Win32 clock_gettime() implementation.
- Source: https://github.com/Alexpux/mingw-w64/blob/master/mingw-w64-libraries/winpthreads/src/clock.c
- Public Domain within mingw-w64, included here to simplify linkage.
- Tested on Win10 64bit w/ TestTextRendererNEWT00, all values are OK
