TIMEZONE setting in HP-UX

[Mohamed Galal]

Dears,
I have HP-UX servers in my system. I found that the time was changed in the last 5th April from +2 to +3 although it should be changed in 23rd April according to Egyptian standard.
my question is:
- I need a procedure to change the setting to the correct setting?


here is my details:
===============
here is the contents of /usr/lib/tztab

# Egypt Time, Egypt Daylight Savings Time
EGT-2EGTDST
0 0 25-30 4 2000-2038 0 EGTDST-3
0 0 28-29 8 2000-2038 0 EGT-2
=========================
root% more /etc/TIMEZONE
TZ=EGT-2EGTDST
export TZ
=========================
root% date
Mon Apr 6 20:25:16 EGTDST 2009
root% date -u
Mon Apr 6 17:25:22 UTC 2009
=========================
root% perl dst.pl

Sun Apr 05 01:59:59 EGT 2009 --> Sun Apr 05 03:00:00 EGTDST 2009

Sun Oct 25 01:59:59 EGTDST 2009 --> Sun Oct 25 01:00:00 EGT 2009

=========================

See man page on command 'set_parms' and specifically 'set_parms timezone'. This interactive command will walk you through the question that you need to answer automajically.

"Sun Apr 05 01:59:59 EGT 2009 --> Sun Apr 05 03:00:00 EGTDST 2009"

doesn't appear to match the tztab file as presented... from what's there, I'd have expected the time change to occur on Sunday 4/26????

i thought egypt transitioned at midnight the last friday of the month (which doesn't seem to match the tztab either) but I've been unable to confirm that

The week interval in both lines in not a full week and both lines are probably ignored. The "25-30" should be "24-30" and the "28-29" should be "25-31".
Fix those numbers and try the dst.pl again.

Exactly. Some previous threads:
