For example there is this gem, where someone is pointing out that there is a mistake in how a brief time zone change in East Berlin in 1945 is handled wrong:
> The mistake in tz2007k is that the special 1945 rules for East Berlin and the German Sowjet Zone [...] are applied to Germany in general. The modifications return Europe/Berlin to the standard rules [...] and introduce a new zone Europe/BerlinEast [...].
