Current Time in GMT + 10 Zone
About GMT+10
GMT+10 is ten hours ahead of Greenwich Mean Time. It is known as Australian Eastern Standard Time (AEST), covering major cities like Sydney, Melbourne, and Brisbane. It's also used in Papua New Guinea and Guam. New South Wales, Victoria, and Tasmania observe DST, while Queensland does not.
UTC Offset: GMT+10
What is GMT+10?
GMT+10 means Greenwich Mean Time 10 hours ahead of the Greenwich meridian, the historical reference line running through the Royal Observatory in London. GMT offsets are the everyday way many countries, broadcasters, and travel timetables describe their local time relative to the UK.
Note that some of the countries listed below sit on GMT+10 for only part of the year: when daylight saving time starts or ends they move one hour, so always check the live local times shown on this page or on each country's own page.
GMT+10 vs UTC+10
For everyday purposes GMT+10 and UTC+10 are the same wall-clock time. GMT is the traditional name based on mean solar time at Greenwich, while UTC is the modern atomic-time standard used by computers and aviation. If you are setting a meeting or catching a flight, either works; if you are configuring a server, use UTC+10.

GMT+10: A Fixed Offset Across the Pacific and Beyond
Fixed Offset vs. Named Time Zone
A fixed offset like GMT+10 is simply a constant difference from UTC, with no seasonal changes. In contrast, a named time zone, such as Australian Eastern Standard Time (AEST) or Vladivostok Time (VLAT), can include DST rules that shift the offset during summer months. For example, while GMT+10 is always UTC+10, AEST is only UTC+10 during standard time; during DST, it becomes Australian Eastern Daylight Time (AEDT) at UTC+11. Therefore, the list of countries and regions on GMT+10 is not static: areas that observe DST move on and off this offset seasonally.
Regions and Cities on GMT+10
Australia: The states of Queensland (Brisbane, Lindeman) and the Australian External Territories (e.g., Lord Howe Island uses a different offset) are on GMT+10 year-round. Queensland does not observe DST, so it remains at GMT+10 while neighboring states like New South Wales shift to GMT+11 during summer.
Russia: Vladivostok Time (VLAT) covers the Primorsky Krai, Khabarovsk Krai, Sakha Republic (western part), and the Jewish Autonomous Oblast. The city of Vladivostok and Ust-Nera are on GMT+10, but Russia used to have DST; currently, Russia stays on standard time year-round, so these regions remain at GMT+10 permanently.
Papua New Guinea: The entire country uses Papua New Guinea Time (PGT), which is GMT+10. Port Moresby, the capital, and other major centers like Lae and Mount Hagen are on this offset.
Guam and Northern Mariana Islands: Both U.S. territories use Chamorro Standard Time (ChST), which is GMT+10. Guam (Hagåtña) and Saipan are on this offset year-round, as they do not observe DST.
Micronesia: The Federated States of Micronesia uses GMT+10 for the states of Chuuk (Truk) and Yap. The other states, Kosrae and Pohnpei, are on GMT+11.
Antarctica: Research stations like Dumont d'Urville (France) use GMT+10 year-round, though many Antarctic stations shift to DST in summer.
Military and Aviation Designations
In military time zone lettering, GMT+10 is designated as "Kilo" (K). This is used in aviation and maritime communications to denote the offset. For example, 1400K means 14:00 hours at GMT+10.
Practical Scheduling Notes
When scheduling across GMT+10, remember that regions like Queensland (Australia) do not observe DST, while neighboring states do. This means during the Australian summer (October to March), Brisbane is 1 hour behind Sydney and Melbourne (which are on GMT+11). Similarly, Vladivostok is 7 hours ahead of Moscow during winter, but 8 hours ahead during Moscow's DST (though Russia no longer observes DST). For international calls, note that Guam and Saipan are 15 hours ahead of Eastern Standard Time (EST) in the United States during EST's standard time.
