If that's the way you "fix" your broken configuration, why not use
a more indicative string so that people know your system's broken:

$ date; TZ=UTC date; TZ=UTC0 date; TZ=XXX date; TZ=XXX0 date
Wed Apr 10 10:48:36 CDT 2019
Wed Apr 10 15:48:36 UTC 2019
Wed Apr 10 15:48:36 UTC 2019
Wed Apr 10 15:48:36 XXX 2019
Wed Apr 10 15:48:36 XXX 2019
$

David.
