It should not :-)

This probably means that your timezone (or the NTP server's timezone) is not configured properly.

You could try another NTP server, or check your timezone config.

Check your /etc/TIMEZONE file.

This is almost certainly a problem with the timezone setting on your machine. NTP uses GMT to allow it to work across timezones. My guess is that your system is set for a timezone that uses Daylight Savings time.

What version of Solaris are you running?

Has PKST changed dates in the last few years?

Sun regularly update the timezone files when daylight savings dates change.

jlevie : yes. But what if the remote server (if it's a master server) stupidly changes it's time manually to respect DST ??

naufal, I suggest you try the following :

zdump (or maybe zic, I don't remember on Solaris) :

zdump -v PKST

It should show 4 lines. 2 in 1901 (epoch) and 2 in 2038.

If it's right, thern I strongly suggest you switch to another NTP server.

Now, on Linux, you can try the zdump trick :

First, do a date, and check for the timezone name.

Then, dump it's rules (e.g: PKST) :

zdump -v PKST
