United Kingdom uses United Kingdom Time (GMT/BST), IANA identifier Europe/London.
Greenwich Mean Time is measured at the Royal Observatory in Greenwich and is the historical basis for the modern UTC standard.
The UK switches between GMT (UTC +00:00) in winter and British Summer Time (UTC +01:00) from late March to late October, so UTC and London time are only identical for part of the year.
The second panel shows UTC beside the local clock, and the roller lets you check any UTC hour against GMT/BST — useful when a call, deadline or flight time is published in UTC.
