Subject[PATCH 2.6] fix POSIX timers expire before their scheduled time
From
Date
POSIX says: POSIX timers should not expire before their scheduled time.

Due to the timer started between jiffies, there are cases that the timer
will expire before its scheduled time.
This patch ensures timers will not expire early.
