Time to spring forward

CLOCKS and other time-pieces should be put forward by one hour on Sunday (March 25) as British Summer Time begins for another year. The official time changes at 1 a.m., moving forward to 2 a.m. across the UK.

Summer time was first defined in an Act of Parliament in 1916. The clocks were moved one hour ahead of GMT from the spring to the autumn.

During World War Two, double summer time (two hours in advance) was introduced. Since the 1980s, all western and central Europe has co-ordinated the date and time of clock changes.
