> America/Nuuk does daylight savings at -01:00 (yes, with a negative)

Somewhat related: Europe/Dublin has a negative DST offset. Irish DST runs through the European winter (i.e. the opposite of the other European timezones).

(More details here: https://github.com/golang/go/issues/56743#issuecomment-13157... )

Edit: To be clear: the quote is referring to a negative DST start, rather than a negative DST offset.

In the github repo the article links, there is a large number of comments about the Europe/Dublin time zone in the europe file, including one quote from Ulysses: https://github.com/eggert/tz/blob/7748036bace8562b9c047f368c...

I think you misread that. America/Nuuk doesn't have reverse DST (which is easily solved by just switching DST and non-DST around). It starts DST at a negative offset because the offset is defined as relative to the previous day.

Yes, this is indeed a different situation and my comment doesn't make that clear. Thank for pointing that out. I've made an edit.
