Jason Evans b732c395b7 Refine nstime_update(). ... Add missing #include <time.h>. The critical time facilities appear to have been transitively included via unistd.h and sys/time.h, but in principle this omission was capable of having caused clock_gettime(CLOCK_MONOTONIC, ...) to have been overlooked in favor of gettimeofday(), which in turn could cause spurious non-monotonic time updates. Refactor nstime_get() out of nstime_update() and add configure tests for all variants. Add CLOCK_MONOTONIC_RAW support (Linux-specific) and mach_absolute_time() support (OS X-specific). Do not fall back to clock_gettime(CLOCK_REALTIME, ...). This was a fragile Linux-specific workaround, which we're unlikely to use at all now that clock_gettime(CLOCK_MONOTONIC_RAW, ...) is supported, and if we have no choice besides non-monotonic clocks, gettimeofday() is only incrementally worse.		2016-10-10 11:40:46 -07:00
