Ah, yes. Very nice. I taught a couple of DB2 courses for

Time updates due DST..again we have much discussion.
But I would like any comments regarding z/OS time, when the customers
accessing the system are not physically located in the same time zone.
I believe the ISO standards support local time display with timezone infomation

Although we support applications accessed in other time zones, some of which
do have Daylight Savings adjustments, we do not change our machine time.
The users see local time via adjustments made by the application performing
the display.

In the z/OS MVS world the time zone is stored in CVTLDTO, which only

Perhaps you already know about this, but there is something called a

Yep, you definitely need Coupling Links. And the STP feature is a priced
one, about the same (perhaps slightly less) than the Timer.
The redbooks Shane mentioned are the go. There's quite a bit to it.
