[RndTbl] minor DST problem with Red Hat/Fedora "legacy" systems

If you're still running Red Hat or Fedora Linux systems that were being 
updated by the Fedora Legacy project before it was shut down, you should 
have received the tzdata update last year to correct the Daylight Saving 
Time switchover for this year.  However, the updates from 
fedoralegacy.org only installed the new /usr/share/zoneinfo files, but 
didn't update /etc/localtime from that.  (On RH/FC systems, 
/etc/localtime is a copy of the appropriate zoneinfo file, not a 
symbolic link.)

What I found is that for these systems (RH9, FC1-3), I needed to do the 

     cp -p /usr/share/zoneinfo/America/Winnipeg /etc/localtime

After that, I either rebooted the system, or restarted these services: 
syslog, crond, xinetd, sendmail, httpd.  FC4 updated itself 
automatically last spring, so as long as you rebooted since then, the 
DST change should have happened without a snag.  FC5-6 had the changes 
at release time.

I also managed to update a very old Red Hat 6.2 system by copying the 
zoneinfo file from a Red Hat 9 system updated by fedoralegacy.

Just thought these tips might be of help if you're supporting legacy 
linux boxes.
