Description Lars Engels freebsd_committer freebsd_triage 2016-04-18 13:12:34 UTC 
In tzsetup when you select "Germany" as timezone another window pops-up asking if you live "Busingen" or "most locations".

Büsingen is a tiny German exclave in Switzerland with 1,300 citizens. The probability that this small village will ever be in a different timezone than the rest of Germany is nearly zero.

Please remove the pop-up window and do no longer confuse German users.

tzsetup operates on the list of zones from tzdata, 3rd-party library/dataset, FreeBSD uses it as-is, without modifications. Apparently at some point DST rules in Busingen and DD/DE were different which by tzdata rules warrants creating dedicated record for it:

# From Tobias Conradi (2011-09-12):
# Büsingen <http://www.buesingen.de>, surrounded by the Swiss canton
# Schaffhausen, did not start observing DST in 1980 as the rest of DE
# (West Germany at that time) and DD (East Germany at that time) did.
# DD merged into DE, the area is currently covered by code DE in ISO 3166-1,
# which in turn is covered by the zone Europe/Berlin.
