Can you try a specific server?

Also, I found that ntpdate was less ful to me than full ntp (which
now comes with a 'quick' option). The ntp docs say that they are hoping
now that ntpdate dies a gracefull death as people switch to ntp.

I've had good luck with the command
# ntpdate-debian
which is also in the ntpdate package. You don't need to give it any
arguments -- it will automatically look for one of the debian NTP
servers: [0-3].debian.pool.ntp.org

Actually, it looks in /etc/default/ntpdate for whatever NTP servers
you have defined.

I changed it from the Debian pool to my ISP's ntp server.

I assume you are in Asia. If so, run the following script and
examine the output. Pick three hosts that look best and use them in
place of "3.asia.pool.ntp.org".

Script:

--------cut here---------------
for i in 0 1 2 3
do
host $i.asia.pool.ntp.org
done | while read x
echo ""
do y="$(echo $x | sed 's/^.*has address //')"
ping -c10 -q $y
host $y
done
--------cut here---------------

Criteria for a "good" host:

no more than 10% packet loss.
max round trip time is acceptably low
deviation (mdev or stddev, depending on which version of ping) of
round trip time is acceptably low.

Enjoy!

Rick
