Hi Andrea,

Thanks for your email. It actually made me look into the differences between
the two — I am not sure I had considered this at all before, and had assumed
they were some kind of internal alias… if I thought about it at all.
In practice, TZ=UTC and TZ=UTC0 do behave identically, but using UTC0 bypasses
any kind of lookup in your timezone database. It appears that glibc can
parse "UTC0" internally, whilst "UTC" will require poking in
/usr/share/zoneinfo.
(Similar with "Etc/UTC"). Perhaps if you don't have tzdata installed, "UTC"
won't work?
I will say that "UTC0" will appear unfamiliar to most developers, so saving
one disk lookup — that is probably already cached! — is probably a little
silly in a build of a Debian package.
Still, interesting to know. :) Thanks again for prompting me to look it up.
Best wishes,
