MST vs GST
MST (Mountain Standard Time) runs at UTC−7 and GST (Gulf Standard Time) at UTC+4. GST is normally 11 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. GST stays at UTC+4 all year round — it does not observe daylight saving time.
