It now works most excellently across all supported operating sytsems (earlier it didn't work on NT and XNU). Demo code is available in examples/clock.c and this change also adds some of the newer ANSI C time functions like timespec_get(), plus timespec_getres() which hasn't even come out yet as it's C23
