I'm not seeing anything that has to do with setting the dates when EDT
starts and EST begins (and vice versa). I've already set the timezone to
Eastern time. That's not the problems.

If one were to search Google Newsgroups a bit, one might find:

It has been posted here many times.
Get the file
tzdata2007a.tar.gz /* look for a newer file, just in case */
from many places on the web
Go to the directory where you downloaded it
tar -xzf tzdata2007a.tar.gz
zic northamerica
rm /etc/localtime
cp /usr/share/zoneinfo/America/Vancouver /etc/localtime
(or if you are unfortunate enough not to live in Vancouver, use the nearest
large city with the same timezone as you have)
That is it.
If you have a program which runs continuously and needs the correct local
time, restart that program. Otherwise sit back and enjoy

OR
urpmi timezone-2007h-1.1mdv

Cheers!

Thank you very much. This is very helpful.

You have not updated your system in a long long long time, not surprizing
since Mandrake 10.1 has been out of support for years.
You heed to get a tzdata file Just lift it out of one of the more recent
mandrivas (they just released tzdata 2007h) and install it with rpm. tzdata
file formats have not changed in a long time, although the data has.


nux dows not "enable Daylight time by rightclicking" It has a file,
specially designed for your particular location, which tells the system
exactly when Daylight Saving time stops and starts.

You need to upgrade your timezone files.At least the one for the timezone
you are in. You can do this manually if you just want to overwrite the
old files. Just ssh into a newer system and copy theirs over to yours.
IIRC, you need /etc/localtime and then the file it gets created from.
look for /usr/share/zoneinfo dir and replace the one for your location
with the new one. I think that's all. Or just ssh into anyone anywhere
and copy your location file and then copy it to /etc/localtime. that's
all that gets done when you set the time zone anyway.

[wes@wes2 ~]$ md5sum /etc/localtime
6540624294b1193e22ed7a15692f2de7 /etc/localtime
[wes@wes2 ~]$ md5sum /usr/share/zoneinfo/America/Chicago
6540624294b1193e22ed7a15692f2de7 /usr/share/zoneinfo/America/Chicago
[wes@wes2 ~]$

Thank you for the explanation. I'm not finding any /etc/localtime
directory or file. There is a /etc/locale/en_US folder with a file called
LC_TIME in it, but I don't know if that's the same. There is a
/usr/share/zoneinfo directory, or more specifically a
/usr/share/zoneinfo/US directory with a file called Eastern inside it.

Look again. It may be a symlink pointing to the file in /usr/share/
zoneinfo directory.

It's not.

That's the one for eastern time zone (about 3 years ago). They don't use
that format now. ~/America covers all of the Americas.

Install a recent tzinfo rpm. (eg theone just released which contains 2007h)

rpm -Uhv timezone-2007h-1.1mdv2007.0.i586.rpm

cp /usr/share/zoneinfo/America/New_York /etc/localtime
(Assuming you live in New York)
Then edit /etc/sysconfig/clock and set UTC=true
Then do
hwclock --systohc -u

Then relax, except of course you have a seriousl y out of date distro which
is accumulating serious security bugs.
