Hi,

I just received an email from someone at IBM Global Services asking 
me if IPLINFO would require any changes / updates to support the
DST changes in 2007.  I've heard of a lot of companies writing
all their vendors to ask the same question (I guess that is a 
good thing  - wonder if someone here is doing that). 

Does anyone know of any z/OS software that will require changes? 
I can't think of anything that does.  In fact, I know shops that
have changed over in the past on Friday evening for example instead
of Sunday morning.  All the software that runs on z/OS gets its time
information from z/OS, right?  

The only "z/OS" fix I can think of would be for z/OS Unix to support
changes to the TZ environment variable. It already supports a way 
to specify when DST starts and ends but the default it is based on
the (current) American rules (first Sunday in April / last Sunday in 
October).  I assume there is or will be a APAR to change the default
behavior. I wonder if the fix will go back beyond currently supported 
versions of z/OS?  Y2K fixes went back beyond the current supported 
releases at the time. 

Regards,

Mark
