Thanks for the information. I am unable to use as indicated above. I
am using SUSE linux. The putput of "ntpq -p"  at my setup is :

remote           refid      st t when poll reach   delay   offset
*LOCAL(0)        LOCAL(0)        10 l   50   64   17    0.000
0.000   0.004

What  could be wrong here ?

I get the following error when I try "ntpdate ",
# ntpdate -u
14 Feb 18:17:48 ntpdate[13584]: no server suitable for synchronization

I want to use SUSE as time server and by not synchronizing it to
external time server.

Thanks in advance for the help.
