British Summer Time
Since so many people get confused, let's clear this up...
We are currently in GMT and there is...
left until BST.
The above is a countdown until GMT
becomes GMT+1. This is called British Summer Time (BST)
and involves putting your clock forward 1 hour.
(The clocks go forward on Sunday, March 25th 2018 at 01:00am GMT, losing you an extra hour in bed.)
