System time is fast !!

[Simon R Wootton]

I have an L class server runninh HPUX 11i. My problem is simple, the system clock is fast, it's probably gaining 1 minute/week - any idea's or solutions ?

You'll need to setup a time server and use NTP to sync your clock to stop it gaining.

See man xntpd
Its easy to setup.

Hi,
You can use NTP(network time protocol)
If you need help on NTP pls. let us know.

Hi,

You can try to use NTP to sychronize your server to others.
The NTP protocol will select itself the best server to synchronize the others.
Edit the file /etc/ntp.conf, /etc/rc.config.d/netdaemons.
Then start xntpd using /sbin/init.d/xntpd start.

You can either use SAM.

Hope this help,

Of course you can use NTP to keep nicety of the clock! But now you can use SAM to change your clock first! Please stop certain service such as DB application before modify the clock!

Sync that ntp to an outside internet source like the gateway of your ISP.

I have several servers, some run fast, some run slow, some keep pretty darn good time. This is a fact of life with electronics.

Also in ntp.conf, there is an entry for what they call the 'driftfile.' This writes to a file that you can look at to see the last timestep the system took. This can be useful to see if theings are going from kind of bad to very bad as far as time goes. (A system losing lots of time could be having unseen hardware problems, etc.) Plus, as most SA's are curious in nature, it is nice to see what your system is doing all the time.

The format is 'driftfile /etc/drift.file' where /etc/driftfile is the file for it to write to.

Hope it helps
