How many hours is UTC behind MIST?
As abbreviations, MIST is always 11 hours ahead of UTC: UTC is UTC+0 and MIST is UTC+11. To convert, add 11 hours.
Check which label you actually need: MIST (Australian Eastern Time is on AEST today). A time written with an abbreviation that is not in use is usually meant as the local time, so convert between the places instead: right now MIST is 10 hours ahead of UTC.
