Daylight savings
From Tardis Wiki, the free Doctor Who reference
In 21st century England, daylight savings was a yearly event when the clocks were changed, skipping an hour. This caused disturbances to some people's sleep patterns but was not otherwise intended as an actual manipulation of Time. However, Faction Paradox attempted to use a ritual to steal the "missing" hours for themselves. (HOMEVID: Daylight Savings)
British Summertime began in early 2005 on a Sunday morning at 01:00am when the clocks went forwards.
