However, if you have an analogue clock, or the time displays on kitchen appliances like ovens, microwaves etc. you will have to change these yourself.
But count yourself lucky you don’t live or work in Windsor Castle – as changing the hundreds of clocks there takes hours.
Horological conservator Fjodor van den Broke spends a staggering 16 hours changing the 400 clocks in the 900-year-old castle each spring and autumn.
Fjodor told the BBC: “It’s just myself, and I have one colleague at Buckingham Palace who changes all the clocks there.”
