This is a Scott Wood patch against 2.6.3.


Use gettimeofday() rather than xtime.tv_sec in sys_time(), since
sys_stime() uses settimeofday() and thus subtracts the subtick correction
from the new xtime.

stime() used settimeofday(), but time() did not use gettimeofday().  Since
settimeofday() subtracts out the current intra-tick correction, and nsec
was 0 (since stime() only allows seconds), this resulted in xtime being
slightly earlier than the time that was set.

If time() had used gettimeofday(), the correction would have been applied,
and everything would be fine.  However, instead time just reads the current
xtime.tv_sec, so if time() is called immediately after stime(), you'll
usually get a value one second earlier.
