I don't disagree that the TZ default for z/OS Unix should be derived from
the z/OS TIMEZONE offset.

But the RFE that I submitted is about more than setting TZ - it is about
having dubbed processes inherit their environment variables from the init
process.   Also, read the RFE and you will see that the suggestion is that
there be a system and user OMVS segment level option to control whether
blind dubbed processes should inherit their environment or not.
