System clock always wrong

My system clock is always off by a few hours. I managed to set it with ntpdate once, but after rebooting it's wrong again. My CMOS battery works fine and the time is correct in Windows.

It is precisely N hours where N is integer? Do you have right time zone selected?

What do you get after egrep ^TIMEZONE=\|^CLOCK= /etc/conf.d/clock?

If I recall correctly I don't remember if it was in the handbook or a comment in the "/etc/conf.d/clock" it used to say if you dual boot with windows you should set that file to local or you will keep getting an incorrect time.

I was getting this exact problem despite following the instructions in the handbook:
http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml?part=1&chap=8#doc_chap3

I didn't know I'm supposed to edit hwclock...
Who should we contact to update the handbook to say: "either use /etc/conf.d/clock or /etc/conf.d/hwclock" ?

jsowoc,

The handbook is written around baselayout1 as that is what stable gentoo provides.
With baselayout2, the setup changes and there is a migration guide to ensure an smooth transition.

clock in my box was also not working...didnt know why though, as the /etc/conf.d/clock was correct.I removed it and use /etc/conf.d/hwclock and clock working correct.
But I still have that warning Factory settings of the clock as no /etc/conf.d/clock in there...if use this file I get 2hrs ahead of my time regardless of the settings in there.
Where can I tell the system to check /etc/conf.d/hwclock instead?

P:S
baselayout-->sys-apps/baselayout: 1.12.11.1

muhsinzubeir,

There are two scenarios.

1. You dual boot with windows.
In your BIOS, set the time by your wristwatch.
copy /usr/share/zoneinfo/localtime to /etc/localtime
In your /etc/conf.d/clock set your timezone to localtime
You must boot into Windows to get changes in daylight saving time to take effect because windows changes your BIOS time.

2. You use Linux Only
In your BIOS, set the time to UTC
copy /usr/share/zoneinfo/<city_near_you> to /etc/localtime
In your /etc/conf.d/clock set your timezone to <city_near_you>
Daylight savings time changes happen in real time.

thanks for clearing that up neddy, i ended up changing the clock for DST in the bios, which gives the same effect as you say.
