What's the option to select FMT8/9 DSCBs in:
o JCL DD statements?
o TSO ALLOCATE?
o BPXWDYN
So, I assume the maximum value of DS9TIME is 8.64e10 for days
having 24 hours, 8.28e10 for days having 23 hours, and 9.00e10
for days having 25 hours.
Does IBM provide a utility, API, or sample code to format DS9TIME
as "hh:mm:ss.uuuuuu zone" for display?
So on 2020-11-01, 5.40e9 might display as 01:30:00 MDT,
and 9.00e9 might display as 01:30:00 MST, right?
"*local* time"!? WTF!? Where did IBM designers have their heads stuck?
