Yes, glibc is wrongly attempting to process strings as filenames
first, then as POSIX-format TZ strings.

This is OK, so long as all the file names actually installed in thesystem cannot be confused with valid POSIX-format TZ strings. That isthe case with the standard time zone database normally installed inGNU/Linux systems (at least it is now; long ago there were ambiguitiesbut they were removed many years ago).
