However:
<https://www.ibm.com/docs/en/zos/2.5.0?topic=variable-command-format>
Format
TZ= standardHH[:MM[:SS]] [daylight[HH[:MM[:SS:]]]
[,startdate[/starttime],enddate[/endtime]] ]
Parsing that is the "exercise for the customer." It's the sort of thing that
DFSORT or
ICETOOL is good at. Does DFSORT provide conversion of arcuival (E)TOD
timestamps to displayable local time? Does IBM ship OMVS with tZ in
/etc/profile
configured for various customers' locales?
It's far better outside the z/OS world: <https://www.iana.org/time-zones>
... represent the history of local time ...
