Through this it kinda has become API. Which doesn't mean it can't be
changed, but can we please make sure that the new format is as well
documented as the old one, i.e. please update that man page along with
this new feature.

My understanding is that the format (as documented) hasn't actually changed, but the data provided in the tzdata package now contains negative DST offsets for the first time, something that certain implementations are not prepared to deal with.


Correct!  Thanks for clarifying this Florian!
