GST vs MST
GST (Gulf Standard Time) runs at UTC+4 and MST (Mountain Standard Time) at UTC−7. MST is normally 11 hours behind GST.
GST stays at UTC+4 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.
