All you need to know. Clocks should be put back 60 minutes at 2am on Sunday as the UK reverts to Greenwich Mean Time (GMT). We will stay on GMT until March 30 2014. The result of the change is that it will be lighter in the mornings, but at the other end of the day, the evenings will get darker earlier.
