Problems with Timezone

Frank Schneider_2 — Mon, 20 Jun 2005 06:03:10 GMT

Hello all,

i have running an a-class server with hp-ux 11.00

All users, but not rrot, are using the false timezone. Root is using MET-1METDST, the others are using EDT.

I have searched in /etc/TIMEZONE, in /etc/profile and in the .profile`s from the users.

Is there any idea what i have to change that the users are using the right timezone?

thx for help... :-)

my /etc/TIMEZONE looks like this:

TZ=EST5EDT
export TZ

Are you running NTP??

ps -ef | grep ntp
grep -v "^\#" /etc/ntp.conf

Are the users "sourcing" in any other PROFILES from their .profiles ?

Did you check the other PROFILES like .kshrc ?

Frank,

I would suggest re-setting the system timezone to make sure that's right:

/sbin/set_parms timezone

i cannot use set_parms cause set_parms needs an reboot to take affect.

But yes, we have running xntpd. Some of the users are sourcing other profiles, but there is no export=TZ in the profiles. My /etc/TIMEZONE looks "TZ=MET-1METDST". I dont know why the users do not source it....
The /etc/ntp.conf looks good.

Can you have a non-root user go to a shell prompt and do this:

echo $TZ

env

set

and post the results?

as root it returns the same.

Re: Problems with Timezone

harry d brown jr — Mon, 20 Jun 2005 07:49:33 GMT

From "man timezone":

1) if the environment variable TZ is present, it takes precedence.

2) if TZ is not present, then the value contained in /etc/default/tz is used for the default.

3) if /etc/default/tz is not set then the default value is equivalent to EST5EDT (Eastern Standard Time) of the USA.

/etc/default/tz can be modified for an appropriate default value for timezone.

Does "grep MET /usr/lib/tztab" return this:

[root@vpart1 /]# grep MET /usr/lib/tztab
MET-1METDST
0 3 25-31 3 1983-2038 0 METDST-2
0 2 24-30 9 1983-1995 0 MET-1
0 2 25-31 10 1996-2038 0 MET-1

Re: Problems with Timezone

Thx for the cut of manpage... The grep returns the same as your output. But now i`ve created an /etc/default/tz with MET-1METDST in it. Now it works.

Why does it not works without it? Maybe i have to check the file permissions?

Is your machine patched to at least the Patch Bundle: http://www1.itrc.hp.com/service/patch/releasePage.do?BC=patch.breadcrumb.main|patch.breadcrumb.bundle|patch.breadcrumb.releaseIndexPage|&releaseId=5013-2091

No it isn`t. But I will do that at the next downtime!

Thank you very much for help! :-)

Re: Problems with Timezone

Bill Hassell — Mon, 20 Jun 2005 09:58:18 GMT

There appears to be a problem in TZ referencing the tztab file. What are the permissions on /usr /usr/lib and /usr/lib/tztab? They should look like this:

# ll -d /usr /usr/lib /usr/lib/tztab
dr-xr-xr-x 25 bin bin 8192 Oct 24 2003 /usr/
dr-xr-xr-x 39 bin bin 16384 May 30 14:45 /usr/lib/
-r--r--r-- 1 bin bin 12794 Nov 14 2000 /usr/lib/tztab

Another way to test is to specify a different TZ value on the command line:

TZ=MST7MDT date
Mon Jun 20 08:41:02 MDT 2005

TZ=PST8PDT date
Mon Jun 20 07:41:37 PDT 2005

These should each produce different times with the chosen timezone shown at the end. If you see EDT for all of these, access to the tztab file may be disabled or TZ was never exported for subprocesses.

And that may the problem: your shell's set command reports on the local variables, but env reports on exported variables. TZ is not there. Find where TZ is set for this user. It should always be set in /etc/profile as:

. /etc/TIMEZONE

VERY IMPORTANT: there is a dot (period) in front of the TIMEZONE shell script. This makes sure that the current shell runs the script and not a subshell. Without the dot, a subshell runs the script, the setting is made and then the subshell goes away and the setting in the local shell (including export) is never made.

Frank Schneider_2 — Tue, 21 Jun 2005 04:09:57 GMT

Hello Bill,

the permissions on the files are set as shown from the output of your post.

I wondering why, it is now so easy! In /etc/TIMEZONE there is no export TZ. There was only TZ=MET-1METDST was in there.

Now my problem is solved... thx! :-)))
