Yes we do, there's one coming up on Sunday. There's going to be another in March.
Silly me - I mis-read the post I was replying to. I thought it said "why do we NEED a clock-change...", not "why do we DO...".
Being a collector of mechanical clocks, I have a major job correcting them every Spring and Autumn, but it's only twice a year, and in Autumn I just have to stop them for an hour.
