But, it can/does cause some problems with things like young children
going to (or coming from) school in the dark.

Standard time gives the kids their best chance of going to school and
coming
When I was a child in Fairbanks, we went to school in the dark and came
home in the dark. Heck, we even ate lunch in the dark!

Leap seconds are a PITA. I'd like to reflect your question
to IBM: What customers' business needs was IBM addressing
in choosing to run the TOD clock on IAT (minus ten seconds),
rather than on UT1

There have been lots of replies referencing the LE callable date routines.
Depending upon what type of date you are looking for, these may well be your
best answer.
HOWEVER,
If all you want to do is know what the offset is from GMT of where your
application is running, then you can easily just

People are mostly happy if the routine is not changed.

NO. As I stated earlier people like routine.
Especially children.
Don't change the clocks, change the stated time they should be at school.

Hi all,
A question has been asked of me to which I think I know the answer, but
not how (in)efficient it would be:
Is there a z/OS-supplied function to convert GMT to local time (or back

Now, I don't yet know in what format the GMT is arriving for
conversion, but it is very likely NOT

For different values of efficient.

At the risk of exciting the ire of other list members, I think you'd
better start coding the Assembler solution. You can use some shortcuts,
