Why do the clocks on all my devices fall out of sync?

Question

Had a power cut three months ago. Set my oven, my microwave and alarm clock to match the time on my phone. After setting them they would have all been within 1 minute of each other roughly.

Three months on, at the time of writing this, my phone reads 10:10, oven 9:56, microwave 10:02 and digital clock 10:11.

That is not normal and insane drift. It’s possible you have dirty electricity at your house.
