IST vs MST
IST (India Standard Time) runs at UTC+5:30 and MST (Mountain Standard Time) at UTC−7. MST is normally 12 hours 30 minutes behind IST.
IST stays at UTC+5:30 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.
