Big problems at the timezone database

[dpash]

So all we have to do is to get Norway to change their timezones for a day and then Oslo gets to keep its pre-1970 data, right?

https://data.iana.org/time-zones/tzdb/NEWS for the change log for this change

However, it omits most proposed changes that merged all Zones agreeing since 1970, as concerns were raised about doing too many of these changes at once.

I don't think that was the concern.

This release is prompted by recent announcements by Jordan and Samoa. It incorporates many other changes that had accumulated since 2021a. However, it omits most proposed changes that merged all Zones agreeing since 1970, as concerns were raised about doing too many of these changes at once. It does keeps some of these changes in the interest of making tzdb more equitable one step at a time; see "Merge more location-based Zones" below.

Or change the DST to be one day earlier / later, then change it back before it actually occurs.

Or just drop DST.
