​Transcript from my z/OS 1.12 system:

$ printenv TZ;date
CST6CDT
Wed Dec 28 14:44:34 CST 2016
$ TZ=UTC date
Wed Dec 28 20:44:43  2016
$ TZ=CET-1CEST-2 date
Wed Dec 28 21:44:53 CET 2016
$ TZ=FAT-1TST-2 date
Wed Dec 28 21:46:19 FAT 2016
$ TZ=CST date
Wed Dec 28 20:47:07  2016


Notice especially the first and last entry. On the last, the date comes out
in UTC even though I use a "valid" code of CST. So I think that, at least
in z/OS 1.12, the TZ must contain the offset from UTC or it is just used as
the "label" in the date command's output.
