Here is IBM's suggestion on AIX 4.3.3
AIX 4.3.3 DST Workaround (Out of support)
ATTENTION: Wait until after November 5, 2006 to make the following
change. If the change is made prior to November 2006, DST will not be
changed until November, even though for 2006, October should still be
You can manually specify when to start and stop DST by setting the TZ
environment variable in the /etc/environment file. An example for the
US Central timezone follows:
TZ=CST6CDT,M3.2.0,M11.1.0"M3.2.0" means to go on DST starting in month
3 (March), week 2, and Day 0 (Sunday).
"M11.1.0" means 1st Sunday in November.
NOTE: Reboot the system before March, 2007 so all processes running
will pick up the new time change.
The question is, if you have vendor application requirements that won't
allow moving to the
appropriate Technology Level's for AIX 5.1, 5.2 and 5.3 to get the
daylight savings fix, why
wouldn't the AIX 4.3.3 work around also apply to other levels of AIX?
Just trying to dowload
the APAR while staying at the same OS level (EX 5.3 TL3) is not
allowed. Same with
AIX 5.2... etc
