System clock set incorrectly on shutdown [SOLVED]

Dr. Frankenbox

Every time I shut down my Gentoo system, it sets the system clock to a seemingly random time and date. It used to be off by six hours, which could have been due to issues with UTC vs. local time (I'm at UTC-6), but lately it's been off by days, weeks, or even years. There's no discernable pattern anymore. I've been having this problem, or a variant of it, for years now, but I've never bothered much about it because as long as ntp is working, it doesn't matter. Still, there are times when it is irritating. If my network connection is down, then I have to set the date and time manually, and every time I load Windows (I dual boot) I have to set the time manually because Windows has a stupid rule about not syncing with an ntp server if the date is wrong. Is there anything I can do about this issue, at least to stop Gentoo from setting the system clock on shutdown?

Hi There

Can you check your /etc/conf.d/clock ?

Don't know if this section helps you.

# Set CLOCK to "UTC" if your system clock is set to UTC (also known as
# Greenwich Mean Time). If your clock is set to the local time, then
# set CLOCK to "local". Note that if you dual boot with Windows, then
# you should set it to "local".

CLOCK="UTC"

Yeah, I definitely noticed that bug back when it was acting as if I'd set CLOCK="UTC" when I'd set CLOCK="local". This is definitely something else now. I don't think it's the battery since I don't seem to be losing my other settings, but so many things are auto-detected now, it's possible I'm just not noticing it. Thanks for the info on CLOCK_SYSTOHC. Oddly, that seems to be set to "no" right now, so I don't know why my system would be setting the hardware clock. I'll try setting it to "yes" once to see if it sets the correct date and time.

i think it is time to replace your RTC battery in the mother board.
also u can set clok to local time upon closing or reboot by set in /etc/clock.
ntpd keeps trackof time sync.
in windows also u have time sync in windows XP
if other windows you can use emsa time sync free utility.
i am also dual booting no problem in clock.

Well, setting CLOCK_SYSTOHC to "yes" seems to have done the trick. Just FYI, using time sync in Windows doesn't set the system clock. (that or there's a bug in my Gentoo install that sets the clock incorrectly when CLOCK_SYSTOHC=no)

i hope you have installed ntp
and ntpd sets your clock and in turn /etc/conf.d/clock set to yes will keep your time upto the minute

Hey all a while ago I vaguely remember hearing about a Daemon that activates as an init script which regulates the time according to a time server or something.

Does this ring a bell for anybody and if so do you know how I can install it?

thanks

Hi, i think that you want ntp (client probably).
