UTC offsets in use right now
A UTC offset is how far a time zone is ahead (+) or behind (−) UTC. Offsets shift when regions switch to or from daylight saving time, so this table is computed live from the IANA time zone database.

UTC offsets explained
Local time = UTC + offset. India uses UTC+5:30, so 12:00 UTC is 17:30 in Mumbai. New York uses UTC−5 in winter and UTC−4 during daylight saving time, so 12:00 UTC is 07:00 or 08:00 there. Offsets range from UTC−12 to UTC+14, and some zones use 30 or 45-minute offsets (for example Nepal, UTC+5:45).

UTC vs GMT
| UTC | GMT | |
|---|---|---|
| What it is | A time standard kept by atomic clocks worldwide | A time zone (and historically, mean solar time at Greenwich) |
| Defined by | International atomic time (TAI) plus leap seconds | The Royal Observatory, Greenwich, London |
| Daylight saving | Never | Never — the UK switches to BST (GMT+1) in summer |
| Used for | Aviation, computing, science, the internet, UTC offsets | Civil time in the UK, Ireland, Portugal and parts of Africa in winter |
| Difference | In everyday use, GMT and UTC show the same time (they differ by under a second) | |
