One answer is to pre-adjust your body clock throughout March ...

Being retired, and thus not tied to the clock, I post-adjust my body clock, starting from when the clocks change. I get up progressively earlier than I would have done in winter but my head thinks I have had a lie-in.

We have a problem with feeding the dog. It has a very strong body clock and will tell us if its feed time is over by five minutes. I adjust the feeding times in the same way as I do for myself but my wife goes straight for the time shown. It gets confused and starts harassing us from any time in the middle of the afternoon until things settle down.
