Re: FALL BACK TIME CHANGE EST

AFAIK there is no reason to shut down at the time change. The only
exception would be if your applications use local time (eg. Time stamps
in data files) that could cause grief. We keep a few of our production
CICS AORs down for this reason but leave our test & UAT regions up to
hopefully catch an error that will prove we need to shut down the
application. Of course not catching an error in test does not prove
there can't be one in production.
Various products (CICS, Omegamon) have commands to refresh local time.

We shutdown TMON-DB2, TMON-CICS and RMF down for an hour. At 2:00 we set
the time back to 1:00 and keep running. We do issue the RESET command in
the running CICS regions.
We do not stop anything else we just keep running.

We also change the TIMEZONE so when we did do the next IPL the clock
will be correct. We did do an IPL on 11/9/2008 but not because of the
time change.

We do the same thing. If anyone knows how to make the change without
sitting idle for an hour we'd like to know that also.

How are you folks handling your "fall back" EST time change ? We set

CLOCK00 with TIMEZONE W.05.00.00, shutdown the system for an hour,
then
IPL and life continues. What are your experiences with SET TIMEZONE ?
Trying
to find a better way than sitting idle for an hour !!
