BST vs MST
BST (British Summer Time) runs at UTC+1 and MST (Mountain Standard Time) at UTC−7. MST is normally 8 hours behind BST.
BST stays at UTC+1 all year round — it does not observe daylight saving time. MST is the standard time (UTC−7); when daylight saving is in effect it becomes MDT (UTC−6). The live clock on this page always shows the current offset.
BST is the summer time of the United Kingdom; in winter the UK is on GMT (UTC+0).
