DST (ended): stand hours logged for upcoming hour

Weird Apple Watch DST issue: DST ended in my country this morning (like in most European countries) and while my Apple Watch (watchOS 10.1) is showing the correct (“new”) time, my stand hours are now logged for the next (upcoming) hour.

(Example: when standing for at least one minute between 12:00 and 13:00 the stand hour is recorded as a white dot / blue line between 13:00 and 14:00, while it’s not even 13:00 yet…)

The iPhone shows them at the correct hour.

A reboot of the Apple Watch did not help…
