it's the sole surviving clock which needs manually updating. The portable battery ones will be long dead. The microwave remains on GMT throughout the year (to avoid fighting with it). The newer gadgets are self-updating via satellite and the computers have the internet (when it's working!).
been on a Zoom call to an elderly relative earlier today, in which she was pleased we'd both remembered the hour change and had just remembered there might be yet another clock to do after already having had help with a couple of them (watch & kitchen).
