(Exiting) Baolin Wang April 30, 2015, 8:14 a.m. UTC
This patch converts the timepsec type to timespec64 type, and converts the
itimerspec type to itimerspec64 type for the k_clock callback functions.

This patch also converts the timespec type to timespec64 type for timekeeping_clocktai()
function which is used only in the posix-timers.c file.
