IBM blundered in not providing a more useful default behavior when TZ is unset
Most UNIX-like systems allow an administrator to supply a default in that case,
more useful than z/OS's inflexible default of GMT.  IBM has justified that 
choice
as providing compatibility with AIX.

z/OS then compounded the offense by providing multiple inconsistent ways in
which developers set TZ (Conway's Law).

There should be a single point of control for time offset interactive shells, 
servers,
and, yes, TSO and batch.  Anything less invites inconsistency.  And,for best 
results:
