Hi All,
I've done the following procedure to verify the unstable date/time being recorded in the hardware clock.
I'm using IBM x343 with FreeBSD 6.2:
1. Rebooted the box. Entered a wrong date/time as:
Date: December 1, 2008
Time: 12:00:00
2. When the box was UP'ed, displayed the date (the box is sync'ed with an
NTP server during start-up).
#date
Thu Feb 12 15:37:57 PHT 2009
It seems correct.
3. Change with a wrong date/time again, then displayed.
# date 0812301200
Tue Dec 30 12:00:00 PHT 2008
# date
Tue Dec 30 12:00:14 PHT 2008
It seems correct.
4. Synchronized the date/time with an NTP Server. Then, displayed the date.
# ntpdate ph.pool.ntp.org
12 Feb 15:40:59 ntpdate[3094]: step time server 202.92.128.201
offset 3814728.167216 sec
# date
Thu Feb 12 15:41:33 PHT 2009
It seems correct.
5. Rebooted the box, then verified the system date/time at the BIOS config.
System Time 07:43:50
System Date Thu 02/12/2009
Wrong TIME? I think the hardware clock was not properly SYNCed with the kernel clock. I've verified this with other box, and same thing happened.
Is there any issues on using date and ntpdate?
Thanks,
Won
