GMT Offset Clock
GMT Offset Clock tracks fixed UTC/GMT offsets rather than named cities, covering every offset from GMT-12:00 to GMT+14:00. It includes half-hour and quarter-hour offsets such as +5:30, +5:45 and +8:45, alongside standard whole-hour zones. Use it when you need the offset itself — say, "UTC+2" — rather than a specific city that happens to sit on it. The clock runs entirely client-side in your browser — no upload, no account, no signup.
Frequently asked questions
What is the difference between GMT Offset Clock and World Clock?
GMT Offset Clock tracks a fixed UTC offset such as GMT+5:30 that never changes, while World Clock tracks named cities and automatically shifts them for daylight saving time.
Does GMT Offset Clock include half-hour and quarter-hour offsets?
Yes — it covers every real-world UTC offset, including +5:30 for India, +5:45 for Nepal, +8:45 for parts of Australia, and +12:45 for the Chatham Islands.
What range of UTC offsets does GMT Offset Clock cover?
It spans the full range used anywhere on Earth, from GMT-12:00 to GMT+14:00.
Is GMT the same as UTC?
For everyday purposes yes — UTC is the modern successor to GMT and the two stay within 0.9 seconds of each other, so GMT Offset Clock’s labels apply to either name.
How is GMT Offset Clock different from Timezone Converter?
GMT Offset Clock shows the live current time at a fixed offset like UTC+2 right now, while Timezone Converter translates a specific date and time you enter between two zones.
