This is unrelated to your issue, but note that the correct TZ string
for UTC is "UTC0", not "UTC". See

Yikes. Can that be actually put into English?

I've read thru it, and the only thing I can come away is that 'if UTC,
then offset is required, and it can be anything from -23 to +23,
including your example 0 meaning no offset from UTC.

As it now reads, theres a ton of ambiguity that needs further
clarification.

There's a discrepency between the historic posix definition of the TZ environment variable, and how it works on a modern system. There's an official workaround that I've never actually seen used in the wild. It doesn't matter in practice.
