>I have installed PHCO_34668

What is the state of this patch?
$ swlist -l patch PHCO_34668

>I change time manually.

Then you broke your system, unless you manually edited tztab(4).

Sujeet,
how do you know the patch did not work ? Did you restart the tztab depenedent processes, like cron etc.

what do you mean by "broke" and how did you determine that it doesn't work?

If you mean that cron jobs are off by the amount of the time change, you need to stop and restart cron.

I installed patches as noted on this bulletin
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&objectID=c00832124

I checked system at 1.57am on that day, it went to 1.59 am and then to 3.00am. So the patch worked.
If you change the date/time manually, I am doubful whether that will get erased after reboot. On my home system, manual changes got erased after reboot. So better to install patches.

Broke as in changing the GMT time on the system instead of fixing tztab(4). This is what time it is now:
$ date; date -u
Tue Mar 20 16:58:02 PDT 2007
Tue Mar 20 23:58:02 UTC 2007

If you manually change tztab, the patches won't work. That's why I asked about the state of the patch.

Manually changing the computer clock to the incorrect value is permanent, until corrected.

Sorry Dennis, those questions were supposed to be to Sujeet.

So, Sujeet:

what do you mean by "broke" and how did you determine that it doesn't work?

If you mean that cron jobs are off by the amount of the time change, you need to stop and restart cron.
