I will perhaps consider doing it at that point, but in ~20 years of being a sysadmin I have never needed to, so… ¯\_(ツ)_/¯

Therefore I optimize for the common case: looking at logs when events do not straddle DST changes.

Nonesense. You can still print the offset and even if you don't, you can always infer which hour you are in from context.
