You will need to edit the TZ variable in /etc/environment.
You will also need to restart all processes that use the $TZ variable.
Best bet is to a quick reboot so that all processes have the new changes
to TZ in their environment.

Hello All,
Can you just use the touch command on /etc/environment or do you
actually have to change the TZ value? When do you have to do this, any
time prior to the time change or after the time change occurs?
Thanks,

Robert,
Unless there is something wrong with the reading of TZ, then,
yes, all you have to do is alter the value of TZ in /etc/environments
file.
Looking at the fixes for 5.1 and 5.2 and some of 5.3, it looks
like the fixes are for SMIT or WLM which you get around by just doing
the editing. Of course, if you install a box at the lower ML level, you
will have to re-do the edit of the TZ variable.
We have some very critical 5.3 boxes that are not at the minimum
TL4 level, but we do not plan, for now, to touch them.... So we may be
editing the TZ variable also.
Good luck

Re: Time Change DST 2007 question
Best I could tell from trying to download the APAR is that for
5.2 you'll need to go to ML8 if you're not already. If you check the
box labelled 'keep me at my current maintenance level', it won't let you
download the fix until you change the level you're at to ML8.
I have some news from a vendor that the workaround for 4.3.X may
work, but it's unverified as of yet... can anyone confirm or deny that
simply changing the TZ environment variable will work?

Admins,
Below I have copied from IBM web page recommended "Apars" for
the DST change in 2007. I want to make sure I have this all ready to
go. I currently have some machines running 5.1 and 5.2 and was
wondering if these below will cover what I need. Also, would any of
these require a reboot of the systems? Thank you for your time in
advance. I am currently in EST.
Thanks
Larry
