Wrong approach because of insufficient information.  It must go
the opposite way, setting MVS time from TZ.  Consider that today
Colorado and Arizona have the same CVTLDTO, but:

    711 $ tail -1 /usr/share/zoneinfo/America/Denver  | tail -1
    MST7MDT,M3.2.0,M11.1.0

    712 $ tail -1 /usr/share/zoneinfo/America/Phoenix | tail -1
    MST7

And those TZ values provide sufficient information to schedule
the (however misconceived) semiannual SET TIMEZONE.
