UTC Offset: UTC+10
What is UTC+10?
UTC+10 is a fixed offset from Coordinated Universal Time: clocks on this offset are always 10 hours ahead of UTC. Unlike a named time zone, a UTC offset never shifts for daylight saving time. Regions that observe DST alternate between two different UTC offsets across the year, which is why the countries listed below can change with the seasons.
In aviation, shipping, and military usage, UTC+10 corresponds to the Kilo time zone (K), written with the letter suffix K in Zulu notation. Pilots and NATO forces use these letter zones so an order like "0800K" is unambiguous worldwide.
UTC+10 vs GMT+10
On a wall clock, UTC+10 and GMT+10 show the same time. The difference is in what they refer to: UTC is the modern standard kept by atomic clocks and used in computing, aviation, and science, while GMT is the older convention based on mean solar time at Greenwich. Technical systems, logs, and APIs should reference UTC+10.

UTC+10: A Fixed Offset Across Continents and Oceans
UTC+10 is a fixed time offset that places clocks 10 hours ahead of Coordinated Universal Time. Unlike named time zones that may shift with daylight saving time, UTC+10 is a constant reference point. However, regions that observe DST move onto and off this offset seasonally, meaning the list of countries and territories at UTC+10 changes throughout the year. This article explores the fixed offset, its permanent residents, and practical scheduling notes for anyone coordinating across this slice of the globe.
What a Fixed UTC Offset Means vs. a Named Time Zone
A fixed UTC offset, like UTC+10, is simply a number: the local time is always UTC plus 10 hours. A named time zone, such as Australian Eastern Standard Time (AEST) or Vladivostok Time (VLAT), is a political construct that may include daylight saving rules. For example, Australia's AEST is UTC+10 during standard time, but parts of Australia shift to Australian Eastern Daylight Time (AEDT, UTC+11) in summer. So while AEST is a named zone that sometimes equals UTC+10, the offset itself never changes. This page is about the constant UTC+10, not any particular named zone.
Regions That Permanently Observe UTC+10
- Australia (Queensland): The state of Queensland, including Brisbane, Cairns, and the Gold Coast, stays on UTC+10 year-round. It does not observe daylight saving time.
- Papua New Guinea: The entire country uses Papua New Guinea Time (PGT), which is UTC+10 all year.
- Russia (Primorsky Krai and parts of Sakha Republic): Vladivostok Time (VLAT) is UTC+10 year-round. This covers Vladivostok, Ust-Nera, and surrounding areas. Russia has not observed DST since 2014.
- Guam and Northern Mariana Islands: Both U.S. territories use Chamorro Standard Time (ChST), which is UTC+10 without DST.
- Micronesia (Chuuk and Yap): The Federated States of Micronesia uses UTC+10 in the states of Chuuk and Yap. The other states (Kosrae and Pohnpei) are on UTC+11.
- Antarctica (Dumont d'Urville Station): The French research station Dumont d'Urville uses UTC+10 year-round. Other Antarctic bases may use different offsets.
Regions That Move On and Off UTC+10 Seasonally
Several areas observe DST and shift to UTC+10 only during their summer months. When not on DST, they use UTC+9 or UTC+11. Key examples include:
- Australia (New South Wales, Victoria, Tasmania, South Australia, Australian Capital Territory): These states observe Australian Eastern Daylight Time (AEDT, UTC+11) in summer and Australian Eastern Standard Time (AEST, UTC+10) in winter. So they are at UTC+10 from April to October (southern hemisphere winter).
- Russia (some regions historically): Russia no longer observes DST, but before 2014, some areas would shift to UTC+10 in summer. Today, all Russian zones are fixed.
Representative Cities at UTC+10
- Brisbane, Australia (Queensland's capital, year-round UTC+10)
- Vladivostok, Russia (Pacific port city, year-round UTC+10)
- Port Moresby, Papua New Guinea (capital, year-round UTC+10)
- Hagåtña, Guam (capital, year-round UTC+10)
- Saipan, Northern Mariana Islands (capital, year-round UTC+10)
- Chuuk, Micronesia (state capital, year-round UTC+10)
- Ust-Nera, Russia (town in Sakha Republic, year-round UTC+10)
- Dumont d'Urville, Antarctica (research station, year-round UTC+10)
- Lindeman, Australia (small town in Queensland, year-round UTC+10)
Practical Scheduling Notes
When coordinating across UTC+10, remember that the offset is constant for some regions but seasonal for others. For example, a meeting at 09:00 UTC+10 in Brisbane is the same time as 09:00 in Vladivostok. But if you're scheduling with Sydney in April, Sydney is also at UTC+10; in January, Sydney is at UTC+11. Always check the current offset for DST-observing locations.
The military uses the letter K for UTC+10 (Kilo time zone). In aviation and maritime contexts, Zulu (Z) is UTC, and UTC+10 is 10 hours ahead. On a clock display, UTC and GMT read the same time, so UTC+10 is also GMT+10 for practical purposes.
IANA Time Zones at This Standard Offset
The following IANA time zone identifiers are permanently at UTC+10 (no DST): Antarctica/DumontDUrville, Asia/Ust-Nera, Asia/Vladivostok, Australia/Brisbane, Australia/Lindeman, Pacific/Chuuk, Pacific/Guam, Pacific/Port_Moresby, Pacific/Saipan.
Frequently Asked Questions
What is the current time in UTC+10?
You can check a world clock for the current time in any UTC+10 location. Since UTC+10 is a fixed offset, the time is always UTC plus 10 hours. For example, if UTC is 12:00, UTC+10 is 22:00.
Does UTC+10 observe daylight saving time?
As a fixed offset, UTC+10 itself does not change. However, some regions that use named zones like AEST (Australian Eastern Standard Time) are at UTC+10 only part of the year. For example, Sydney is on UTC+10 during winter but shifts to UTC+11 in summer. Permanent UTC+10 regions like Queensland, Papua New Guinea, and Vladivostok do not observe DST.
Which countries are always on UTC+10?
Permanent UTC+10 countries and territories include: Australia (Queensland only), Papua New Guinea, Russia (Vladivostok Time zone), Guam, Northern Mariana Islands, and parts of Micronesia (Chuuk and Yap). Additionally, Dumont d'Urville Station in Antarctica uses UTC+10 year-round.
What is the difference between UTC+10 and GMT+10?
For practical purposes, UTC and GMT are identical when displayed on a clock. So UTC+10 and GMT+10 represent the same time offset. The difference is technical: UTC is an atomic time standard, while GMT is a time zone based on solar time. But in everyday use, they are interchangeable.
What military time zone letter corresponds to UTC+10?
The military time zone letter for UTC+10 is K (Kilo). It is used in aviation and military operations to denote a time offset of +10 hours from Zulu (UTC).
Why does Queensland not observe DST while other Australian states do?
Queensland has chosen not to observe daylight saving time due to its tropical and subtropical climate, where longer daylight hours in summer are less impactful. The state held referendums in 1992 and 2005, both resulting in a majority against DST. As a result, Queensland remains on UTC+10 all year, while states like New South Wales and Victoria shift to UTC+11 in summer.
