That sound strange. Here is a transcript of the debconf configuration on
bookworm, using the readline interface to be able to show it in a mail:

Yes, this is actually correct. Contrary to modern conventions, the
POSIX-compatible zones use positive values to refer to POSIX-compatible
zones use positive values to refer to zones west of Greenwich and
negative values for those east of Greenwich.
Since Bookworm, this is be explained in the debconf template where you
select these zones:

Please select your time zone. Contrary to modern conventions, these
POSIX-compatible zones use positive values to refer to zones west of
Greenwich and negative values for those east of Greenwich (e.g., 'Etc/GMT+6'
refers to 6 hours west of Greenwich, commonly called 'UTC-6').

Therefore could you please double check on your system?
