ntpdate and Israel local time

[Dan Shimshoni]

Hello,
  On my desktop at home, when I want to to update the local time (I
live in israel) I run:
ntpdate -s ntpserver.huji.ac.il
And it work OK.
However, there is a server at my work place which I am responsible
for. When I run:
ntpdate -s ntpserver.huji.ac.il
it sets the time to 7 hours earlier (I mean, instead 19:00, it is 12:00).
I assume this has something to do with Time zones, but this machine
has no X windows installed at all so I don't have a GUI for setting time zones.
What causes this error ?
What should I do ? any advice ?

rgs,
DS
