In that case, the convertion of time to 64-bit millisecond value in clock_systmer64() causes some bad times to be returned. Time was converted to milliseconds, then to configured ticks. Precision was lost in the millisecond convertion. The fix is to first convert time to a 64-bit microsecond value, then to the configured tick value. Noted by David Sidrane.

It is only a wrapper around clock_settime() and does not need a trap. gettimeofday() is no longer tried as a core OS interface. gettimeofday has been decremented in POSIX 2008. settimeofday() was never part of POSIX, but I decided to add it to libc as well just for symmetry.

However absolute time was converted to relative time using unsigned integer arithmetic and resulted large ticks count by clock_abstime2ticks, instead of expected negative ticks value. Patch corrects clock_abstime2ticks to return negative ticks, if absolute time is in the past. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@haltian.com>
