A Few Minutes at a Time

I've usually been a little disorientated by losing an hour when we move the clocks forward to enter Summer Time, so I did it differently this year.

I moved my alarm clock forward an hour  on the night before the change, but also moved the alarm time forward by the same amount. Then, every day or two I moved the alarm time back a quarter of an hour or so until it was back at the original time. My inner clock was quite unperturbed, so that seems to be the way to do it.
