Did you realise that when you change your clocks this weekend you are complying with legislation that was introduced to help Britain win the Great War?

Up until the middle of the 19th century time was all a bit haphazard but it didn't seem to matter too much. Until the railways arrived, that is.

The railway company's decided to run their services to London time. In 1880 this Greenwich Mean Time became the legal time.

But in 1916, with the country literally bogged down in the First World War, it was decided to advance the clocks by an hour during the summer to create more daylight working time and, hopefully, create greater efficiency.

Now we comply with the European Union which sees the clocks go forward by one hour on the last Sunday in March and go back again on the last Sunday in October.
