 Posted: Mon Mar 17, 2008 8:53 pm Post subject: /etc/conf.d/clock doesn;t set clock correctly |
 |
|
I have:
CLOCK="UTC"
TIMEZONE="America/Los_Angeles"
Afer I do 'ntpdate' 'date' shows correct time with PDT.
But when I reboot I see that BIOS clock is set not to the UTC but to PDT-1 for some reason.
After I reboot 'date' shows completely wrong time, shifted by 8 hours from what it was before reboot.
What is wrong? |

Hi,
ntpdate is obsolete, use ntpd -x -q instead.
I had suddently the same problem with ntpd and it locked hard everytime ntpd -x -q was unable to synchronize. Tired, I switched from legacy ntpd to openntpd. It isn't as accurate as ntpd and doesn't support certificates (who cares  but works well in the same way as clockspeed. Above all it does not block the boot process.
| Code: |
# cat /etc/conf.d/ntpd
# /etc/conf.d/ntpd: config file for openntpd's ntpd
NTPD_HOME=/var/empty
# See ntpd(8) man page ... some popular options:
# -s Set the time immediately at startup
NTPD_OPTS="-s"
|
| Code: |
# cat /etc/ntpd.conf
# $OpenBSD: ntpd.conf,v 1.7 2004/07/20 17:38:35 henning Exp $
# sample ntpd configuration file, see ntpd.conf(5)
# Addresses to listen on (ntpd does not listen by default)
listen on *
#listen on 127.0.0.1
#listen on ::1
# sync to a single server
#server ntp.example.org
# use a random selection of 8 public stratum 2 servers
# see http://twiki.ntp.org/bin/view/Servers/NTPPoolServers
servers pool.ntp.org
|
Last but not least, do not forget to set your localtime,
| Code: |
# ls /etc/localtime -l
lrwxrwxrwx 1 root root 38 Mar 10 10:46 /etc/localtime -> /usr/share/zoneinfo/America/Los_Angeles

| I am sorry but your response about ntpdate doesn't have much to do with the essence of my question. |

then i invite you to search out the probable response of your problem in the other lines 
An other possibility, set TZ='your_time_zone' in 01timezone.

| In between reboots, if you were running a different operating system which thinks the h/w clock is localtime, and was doing its own time synchronisation then you'd get pretty much what you're seeing. |

I agree with previous post by wjb, that could very well be the problem.
In any case, to fix the wrong hw clock do this: set the time correctly (with ntp) and then run:
$ hwclock --systohc
That will set the hw clock correctly which should make your machine keep the time through reboots (until next time windoze is booted of course). |
