Your test seems incorrect.
$ HISTTIMEFORMAT=%Z
$ history
1 CESTps
[...]
$ TZ=UTC history
1 UTCps
[...]
This is with:
GNU bash, version 5.0.3(1)-release (x86_64-pc-linux-gnu)

Ditto with:
GNU bash, version 4.4.12(1)-release (x86_64-pc-linux-gnu)
Copyright (C) 2016 Free Software Foundation, Inc.
Adding the --posix option doesn't change the behavior related to
the output timezone.

Ditto here.

At least I get a consistent behavior. This suggests something
wrong with your test of TZ.
