There are a number of things that could cause a clock skew, and a number of ways that it can be fixed. I'm afraid we'll need more information.

Situation 1) The newer emachines that have been coming out seem to blast through time, making your clock go more than twice as fast as it should. To fix this, add "no_timer_check" to your kernel boot options.

situation 2) My clock is slowly falling out of sync. This is a harder situation to fix, but not impossible. Often, there's no way to read the clock reliably on your hardware. What you can do is install "ntp" and make sure ntp-client and ntpd are in your default runlevel. Note that this requires constant internet access to keep your clock set, though.

Hopefully you fall under one of these situations and solutions. Good luck!

For ntp, follow the wiki :wink:

Hi nawar,

disabling "spread spectrum" in your BIOS should be the fix in case you use a nforce2 chipset.

Cheers

Thanks guys for your support
Yesterday , I tried one of these soultion which status of add ing "no_timer_check" to the kernel boot line , and am checking the result of clock right now. if it didn't work as expected i will try to use ntp as an alternative , though i don't have permenenat connnection !

Hi nawar!

Using ntp is not really a fix, because the problem must be somewhere else. Maybe it's just the battery on your motherboard.
But to be able to help we would need to know what hardware we're talking about. So what you got?

*gag* Intel hardware- there's your problem. Only use their processors (unless AMD or energy-efficient VIA fit your needs better), not their hardware.

In all seriousness, it sounds like you're going to have to play with kernel settings as mentioned by the previous posters until you find a combination that works. Good luck!

Thanks a lot guys !!
I tested adding the switch "no_timer_check" to the kernel line as mentioned before , and the clocked work fine with me! . though it goes out of sync for 10 or 5 mintues ,its time is approximatly correct ,but what the heck , i can live with that !! , its better than before and i can't complain anymore . Now l can return to my previous status (a one happy gentoo) . hahaha thanks guys for you support you are what form the real gentoo community !
