Nice approach - if you can use it. IPLing is not an option for some
shops. My client has lotsa linux v.m.s and way lighter on the CMS side.
IPLing is not an option. With the light CMS load, critical as it may be,
my testing of SFS, RACF, WAKEUP servers, backups all look OK. But it
does take one rotten apple to spoil the bushel no doubt.

Chuck,
Dig out your "z/VM CP Planning and Administration" manual (or see:
http://publibz.boulder.ibm.com/epubs/pdf/hcsg2b10.pdf )
Look up "TIMEZONE_BOUNDARY Statement", see "Usage Notes" item #2.
In short, your easiest and most reliable course of action is to IPL
after 03:15 AM in the spring and fall. That should be clear enough to
overcome most human error.
Relying on "CP SET TIMEZONE" can work if all your ducks are lined up
properly. But if one duck is out of line, you're "out of duck". :-)
Can you 100% positively guarantee that all your applications can
handle a timezone change gracefully? Will they get upset if they see
a second 02:00 AM, 02:01 AM, 02:02 AM , etc. in the fall? Will they
become hopelessly confused of they miss hour of time between 02:00 and
03:00 AM in the spring? Your call...

Time Change
Being new to z/VM, I was wondering what most users do for the time
change? I noticed several definitions SYSTEM CONFIG that appear to
handle that automagically, but wanted to see if there was a procedure
that needed to be followed to activate it.
Thanks,
