Oh! Thanks for the note. This is probably a very common misconception.
I think the reproducible builds docs have advised setting TZ=UTC in
the past, and I see https://reproducible-builds.org/docs/timezones/
mentions it currently.

Also, codesearch.debian.net reports 95 packages matching TZ=UTC
but only two match TZ=UTC[0-9]. Time for a mass bug filing? :)
