time problem

Amit Dixit_2 — Mon, 27 Sep 2004 03:55:52 GMT

Hi,
I am having 2 server running HP-UX.
Problem I am having is there is an entry in
cronjob to run a script at 2:00 AM on both
the servers but on one server i am getting
time-diff of 2 hours and on another 3 hours
why is it so ??
but the server are having same time as they
are configured to same NTP server.

please check the following.

machine1:/home/sc $grep EET /usr/lib/tztab
EET-2EETDST
0 4 25-31 3 1981-2038 0 EETDST-3
0 3 25-31 10 1981-2038 0 EET-2

machine2:/home/sc $grep EET /usr/lib/tztab
EET-2EETDST
0 4 25-31 3 1981-2038 0 EETDST-3
0 3 24-30 9 1981-1995 0 EET-2
0 3 25-31 10 1996-2038 0 EET-2

will the above entries in the tztab make any difference ?

Thanks,
Amit

Hi Amit,

Could you check below on your servers for the same user.

# whoami
root
# echo $TZ
MET-1METDST
# date

Hi Amit,

What does the script do? Look for something that would cause the second server to run the script for longer.

HTH,

Peter

Hi,

In my system I have for you TZ:

EET-2EETDST
0 4 25-31 3 1981-2038 0 EETDST-3
0 3 24-30 9 1981-1995 0 EET-2
0 3 25-31 10 1996-2038 0 EET-2

But my TZ is not this one, it's PWT0PST...

Hope this'll help you,

Eric Antunes

Hi Amit,

I'm on Hp-UX 11.0

May be you have different patches installed on each server?

Eric,
Can please explain the difference between
the 2 tztab file I have posted why one is
having 2 entries and other having 2 with
byfercation of years from 95 and then
from 96 2038

Why is it so ??

Thanks,
Amit

Every HP machine I have gives the 3 lines result. Maybe your missing a patch on the seconf host. Verify by making a diff between the outputs of
swlist -l patch |sort
on each server.

Fred

Hi,

Do as Fred said or search for uninstalled patches in machine1. One Timezone patch for HP-UX 11.0 is PHCO_27528, is this patch installed on machine1?

Hello Amit,

Rebuild system kernel with timezone of 300 for Eastern time EST5EDT
timezone 300

Once the new kernel is built, confirm timezone with the following command.

grep timezone /stand/system should show timezone of 300
timezone 300

please check this
