tzdata on Lenny and Etch

[Georgi Naplatanov <gosho@oles.biz>]

Hello, I have 2 servers :

Debian i386 Etch
Debian i386 Lenny

and both use ntp to synchronize time and configured on the same timezone 
Europe/Roma and use same time servers, but on Etch the time is 7 minutes 
behind server with Lenny.

On the server with Lenny time is correct.

Where is the problem ?
