Hi,

Likely a “time propagation” problem. Switzerland changed also in the night of Saturday to Sunday. I have checked that the test failed while I was starting to look into the macOS specific code, midnight passed and then test started to succeed again.

I did a quick and rough check using NSCalendar in place of CFGregorianDate and the result was the same, the update to the timezone was only done once march 27 started. Before that, GMT+1 was returned.
