Many a times I have seen the ntpd is using the "local" clock as 
the "source" (in openSUSE it is the default config).   You need to 
remove the "local" clock and set your ntpd to sycn with a ntp server 
(see )

I don't know which distribution you are using but on Fedora I do the following:
1. Setup decent NTP servers in ntp.conf - I set the following
server 0.fedora.pool.ntp.org
server 1.fedora.pool.ntp.org
server 2.fedora.pool.ntp.org

2. Run ntpdate at startup - this basically runs with the following OPTIONS="-U 
ntp -s -b"
   This just does a one time synchronization at startup

3. Run ntpd - this will make sure your time doesn't drift once it has been 
synchronized

Note: Running ntpd as is wont help especially if you are drifting too much - I 
don't remember the threshold but beyond a certain point ntpd wont try to 
correct the time.

Isn't ntpd running? It should do that.

[ilugd] ntp sync to server bt still drift is there

[Subhanjan Ghosh]

Hi,

Facing one problem my server is synced to ntp server but every 2 days there
is a drift of 5 seconds or so then have to manually sync with ntpdate
command.

Any permanent fix as in Redhat Kbase it said that not recommended to put
ntpdate in cron.

Please any solution to this.

With Regards.
Subhanjan
