Time not updated from summer to winter (France) 20 October 2024

I am in France and my iMac, iPhone and iPad are all setup identically with the French timezone, auto update etc etc. This morning when I checked my iPhone, the time had not been updated, same on my iPad and iMac. I checked on the internet and I know all the settings are correct on all three devices. Just heard from a friend and she had same problem this morning. Sh-t show Apple!! So I wonder how many missed appointments there were this morning for people thinking their apple product would update to the correct time overnight. My solution for the moment is to set everything to UK time. Anyone have any idea. And yes, all are updated to latest OS.
