British Summer Time
Since so many people get confused, let's clear this up...
We are currently in BST and there is...
left until GMT.
The above is a countdown until BST
becomes GMT+0. This is called Greenwich Mean Time (GMT)
and involves putting your clock back 1 hour.
(The clocks go backwards on Sunday, October 29th 2017 at 01:00am BST, giving you an extra hour in bed.)
