Time goes back 4 hours on every boot

Well, hello!

I have a problem: everytime I boot my PC, the time is set back 4 hours relative to the time that was set on the last boot. ie, if the clock says 14:00 now, and I reboot, the clock will say 10:00. This all started when I followed the instructions here to set my clock to the right time (it was 10 minutes slow before, but at least none of this magic time-changing happened). So what I want to know is how to fix this so the clock will be normal again.
Here's some output that might be useful...

Code:

hernan@hernan:~ (23.740 MB)$ date

Sat Apr  2 01:55:59 CLT 2005

hernan@hernan:~ (23.740 MB)$ /sbin/hwclock

Sat 02 Apr 2005 05:56:11 AM CLT  -0.178997 seconds

(as you can see, the kernel clock and the hw clock differ).
It probably has something to do with my timezone (CLT: -4 hrs) but I have no idea on how to go about fixing this.
The basic instructions I followed to set the clock were:

Quote:

Summary

* /etc/sysconfig/clock sets whether the hardware clock is stored as UTC or local time.

* Symlink /etc/localtime to /usr/share/zoneinfo/... to set your timezone.

* Run ``date MMDDhhmm'' to set the current system date/time.

* Type ``/sbin/hwclock --systohc [--utc]'' to set the hardware clock.

Thanks for your help,

I have too a delay between hardware clock and system time

Code:

$ date

Tue Apr  5 00:12:00 CEST 2005

$ /sbin/hwclock

Tue Apr  5 00:12:30 2005  -0.809428 seconds

Slackware provides a tool to set zone time, as root try:

Code:

# timeconfig

And you could set your machine time with a time server

Code:

# ntpdate cl.pool.ntp.org

I used here a time server in Chili, look at this list :
http://ntp.isc.org/bin/view/Servers/NTPPoolServers

Thanks! I hope the changes live a reboot =D

If this were a Windows box, I'd suggest just rebooting six times. ;-]

(Sorry. I couldn't resist.)

You could put ' ntpdate cl.pool.ntp.org ' in /etc/rc.d/rc.local ;)
To be more accurate, better is to put it in a crontab, though

I'll have to read up on this crontab stuff.. thanks =D

I had this problem before. It was because I had set my clock to utc but told it local, or the other way around. There's a shutdown script you can modify. I'll try to find it. or you can grep for hwclock in your shutdown scripts.

using "timeconfig" and getting the right time from an ntp server, then doing "/sbin/hwclock --systohc" solved the problem. thanks =D
