i already know ntpdate can do the work
however, it set the time by a long hop, that make so many daemon freeze :(

and now i configured ntpd server
but i failed to make it change time a bit by a bit
all users in my IRC get ping timedout
however, the time is correct now
and i still can't quite get how to avoid big time correction

Have two or more servers listed, and if you have any other boxes in your network, have them peer each other. Make sure you have a driftfile, and that ntp can write to it, especially if your machine reboots alot.

What kind of hardware (motherboard, CPU) are you running ntpd on, and what kind of load does the box have? ntpd requires a good deal of calculation to ensure that it doesn't drift too much.

An example /etc/ntp.conf

server timeserver.some.nearby.edu
server timeserver.some.other-nearby.edu
server timeserver.some.other-other-nearby.edu

peer localmachine1
peer localmachine2

driftfile /etc/ntp.drift

Oh, and pick an NTP server from this list that is in your region:

[eecis.udel.edu...]

If you don't pick one that is in your area, you'll just get a jumpier clock, and annoy a server admin on the far end.

thx drbrain, what's the point to add more than 1 server?
and what's the different between stratum 1 and 2?
i used 1 server from stratum 1 (and i'll adjust the config if i know what i'm doing)
and again, what's the keypoint to avoid long time jumping?
