MST vs GMT
MST (Mountain Standard Time) runs at UTC−7 and GMT (Greenwich Mean Time) at UTC+0. GMT is normally 7 hours ahead of MST.
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. GMT stays at UTC+0 all year round — it does not observe daylight saving time.
