On Linux (as on some other SYS V UNIX) the time (DST) configuration can be
done in more than 1 way. The simplest is to set the TZ env variable. The most
complete (and complicated) way which is used with the Red Hat distribution is
to have a list of rules compiled with `zic'.

You have to do/have:
1. The system use /etc/localtime for the (compiled) time rules.
   To set the zone info to Israel, Tel-Aviv, make a symbolic link.
   i.e. ln -s "../usr/share/zoneinfo/Asia/Tel_Aviv" /etc/localtime

2. The rules must be compiled into the above "linked to" file.
   2.1 Edit a source file of the rules. My source is listed below, it
       has all the rules from 1994 until 2004 (current existing law).
   2.2 Compile it by: zic <rules source>, Please note that the target
       is specified in the source file (last line).

Read the zic and tzset man pages for more information.

Ehud.
