View Full Version : system clock runs too fast?
13th February 2004, 04:04 PM
The hardware clock is fine (verified with hwclock), but the system time seems to be running a bit fast, a day of uptime shows already 2 hours and a couple of minutes ahead of the time it really is.
When setting the time correct again and waiting for 3 minutes and checking it again, it already is about 20 seconds ahead of time, again the hardware clock (checked with hwclock) is running OK.
Anyone else noticed this too?

:?: Are you on hardware that uses HyperThreading technology? Or maybe an IBM Thinkpad?

I too am having this problem and I am running on an IBM Thinkpad i1412 with 512MB RAM and a Celeron 366.
Anyone know why this is happening? It also seems to push the CPU to run at half the correct speed. I'm runnin at 182 MHz instead of 366 MHz :-(

I am also having the same problem on an IBM Thinkpad with Celeron 366. Any way to fix this issue?

Try running adjtimex -a

I had this problem, which is linked to a 50% CPU usage (not very good).
What you have to do is add "no_time_check" in /boot/grub/grub.conf
title Fedora Core (2.6.12-1.1398_FC4)
kernel /vmlinuz-2.6.12-1.1398_FC4 ro root=/dev/vg00/lv00 rhgb quiet no_timer_check
I added the ntpd (network time Protocol) to be sure to be always on the right time at startup.
Everything works fine now, my cpu usage is back to 1% at startup (that is a quick efficient tuning!)
