Commands/services you might be interested in reading about:
date - if you just want to manually set the time
ntpdate - if you want to set it based on an ntp server
ntpd - if you want to keep your system in sync with an ntpserver
ntpq - if you mant to find out whats going on with ntpd

Have you tried webmin? It lets you set this very easily (system and hardware) - and lets you set up a network time connection to update it automatically.

I found tzconfig and hwclock were usefull to set TimeZone and Hardware Clock. --help on either of these will provide help. (find | grep -i tzconfig or find | grep -i hwclock; will locate these files on your drives.)

Post subject:  Setting time

I have the issue where my computer clock battery is slow, and usually falls back a minute or so from my Cable Box, so I just type

date --set hh:mm:ss

Done.

Course this is just the one time solution.

Post subject:  ntpdate gives me an error

I tried to set the system time using ntpdate and it won't connect. The error is:
Code:
root@mythtv:~# ntpdate time.nist.gov
22 May 21:33:34 ntpdate[8585]: the NTP socket is in use, exiting
root@mythtv:~#


I looked around for an answer and some posts say to turn off ntpd.
I am not finding any directions for that on the KnoppMyth forum or wiki.

Help?
Eric

You've already got an NTP daemon running which should be keeping you clock in sync. Is it not working? You can compare it to this - http://www.time.gov/

Code:
ps -A | grep ntpd

will tell you the Process ID (PID) of the ntpd instance
then
Code:
kill XXXX

will stop ntpd (where XXXX is the PID)

I know there are nicer ways but it works for me :-)

Oh, already running? How often does it sync for us? And when is it set to sync for us?

I read the WIKI page http://knoppmythwiki.org/index.php?page ... onizeHowTo
and it it's very existance gave the impression that I needed to activate ntpdate/ntpd.

Is that page outdated? What versions of KnoppMyth does it apply to? It doesn't say.

I tried the ps command. Does this mean that I have 4 instances of ntpd running.
Code:
root@mythtv:/etc/init.d# ps -A | grep ntpd
 4378 ?        00:00:00 ntpd
 8597 ?        00:00:00 ntpd
 8600 ?        00:00:00 ntpd
 8602 ?        00:00:00 ntpd
 8604 ?        00:00:00 ntpd

It syncs from pool.ntp.org, see /etc/ntp.conf for details. It seems to be pretty regular and more than enough to keep my clock within one second of the NIST atomic clock I linked to above.

Yes.

Looks more like 5 to me, which is not a normal state of affairs. Kill 'em all and restart it. As root:
Code:
pkill -9 ntpd
/etc/init.d/ntp-server start

Post subject:  down to 1 ntp instance

OK. That all worked. I rebooted after killing all the instances of ntp.
I'm down to 1.

I think the clock sync is working fine because my pc clock is less than 1 second different from the atomic clock on my wall. Good enough!

Man, those outdated wiki pages are really screwing me up!
Thanks for telling me.

Hi,

A good source of how to is the man pages. I get headaches reading them, eyes bleed also but a wealth of cryptic information :idea:

man ntpd

driftfile driftfile
This command specifies the name of the file use to record the
frequency offset of the local clock oscillator. If the file
exists, it is read at startup in order to set the initial fre-
quency offset and then updated once per hour with the current
frequency offset computed by the daemon. If the file does not
exist or this command is not given, the initial frequency offset
is assume zero. In this case, it may take some hours for the
frequency to stabilize and the residual timing errors to sub-
side.

less /var/lib/ntp/ntp.drift (mine is 43.809) good / bad ?

However it is obvious, cesman has his finger on the pulse :)
Mike
