SBT — Solomon Islands Time
See what SBT means, its UTC+11 offset, whether it uses DST, and how to convert Solomon Islands Time to other zones.
How to Convert SBT to Other Time Zones
Open the SBT converter page: Go to https://www.xconvert.com/time-converter/sbt-time-zone to load the visual comparison grid with Solomon Islands Time (SBT) already shown at UTC+11:00. This page is useful when you need to line up working hours for Pacific-region shipping, NGO coordination in Honiara, or calls with partners in Australia, New Zealand, or East Asia.
Add comparison cities with the + Add City button: Click “+ Add City” and search for cities such as Sydney, Auckland, and Singapore to compare SBT against major business and travel hubs. This is especially practical for regional logistics, government coordination, fisheries, mining support services, and airline itinerary planning, because Solomon Islands schedules are often checked against Australia and Southeast Asia.
Drag on the grid to select a meeting window: Click “Select” if needed, then drag across the SBT row to highlight a time range, such as 9:00 AM to 11:00 AM SBT. That selection lets you instantly see the equivalent in other zones—for example, 9:00 AM SBT is 8:00 AM in Singapore (UTC+8), 10:00 AM in Sydney during Australian Eastern Daylight Time (UTC+11), and 12:00 PM in Auckland during New Zealand Daylight Time (UTC+13), helping you confirm whether a Pacific morning call overlaps with normal office hours elsewhere.
Export and share the selected time: After selecting a range, use the export options that appear: ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. These are useful when you want to send a confirmed cross-border meeting slot to remote teams, attach the event to a calendar invite, or share a link with travel coordinators so everyone sees the appointment in their own local time automatically.
About Solomon Islands Time (SBT)
SBT stands for Solomon Islands Time, the standard time used in the Solomon Islands, a Pacific island nation located east of Papua New Guinea and northeast of Australia. Its exact offset is UTC+11:00, which means local time in SBT is 11 hours ahead of Coordinated Universal Time (UTC) at all times of the year.
Because SBT is a fixed UTC+11 time zone, when it is 12:00 noon UTC, it is 11:00 PM in Solomon Islands on the same calendar day. This offset places Solomon Islands in the same broad hourly band as several other regional time designations, including AEDT, AET, BST, KOST, LHDT, MAGT, NCT, NFT, PONT, SAKT, SRET, VLAST, and VUT, although those abbreviations may apply to different countries or may change seasonally.
The principal urban reference point for this time zone is typically Honiara, the capital of the Solomon Islands, located on Guadalcanal. Honiara is the country's main administrative and commercial center, and SBT is relevant for government operations, port activity, aid and development work, inter-island transport planning, and regional coordination with Australia, Papua New Guinea, Fiji, and New Caledonia.
In practical conversion terms, SBT is 3 hours ahead of Singapore (UTC+8), 1 hour ahead of Japan Standard Time (UTC+9), and the same as UTC+11 zones that are not observing a seasonal shift. That means if it is 9:00 AM in Honiara, it is 6:00 AM in Singapore, 7:00 AM in Tokyo, and 10:00 AM in Auckland only when New Zealand is on standard time rather than daylight time.
SBT and Daylight Saving Time
Solomon Islands Time does not observe daylight saving time, so DST: false means there is no seasonal clock change during the current year or any normal year under the present system. SBT remains UTC+11:00 year-round, with no switch forward and no switch back.
For the current year, 2026, there are no DST transition dates for SBT: it does not switch in March, April, September, October, or November, and it does not change to any alternate abbreviation. This consistency is useful for long-term scheduling because a recurring meeting in SBT stays at the same UTC offset every month, even if the counterpart city—such as Sydney, Auckland, London, or New York—moves due to daylight saving rules.
This matters in real scheduling scenarios because the time difference between SBT and other locations can change even though SBT itself does not. For example, Sydney may match SBT at UTC+11 during Australian daylight saving time, but fall back to UTC+10 outside that period, so a meeting that lines up neatly in January may be one hour different in July.
Frequently Asked Questions
What does SBT stand for?
SBT stands for Solomon Islands Time, the standard time used in the Solomon Islands in the southwest Pacific Ocean. It is the official civil time used for government offices, schools, transport schedules, business operations, and daily life across the country.
Is SBT the same as GMT?
No, SBT is not the same as GMT. GMT is UTC+0, while SBT is UTC+11, so Solomon Islands Time is 11 hours ahead of Greenwich Mean Time; for example, when it is 8:00 AM GMT, it is 7:00 PM SBT the same day.
Which cities use SBT?
The main city associated with SBT is Honiara, the capital of the Solomon Islands and the country's primary administrative and economic center. Other communities across the Solomon Islands also follow the same national time standard, but Honiara is the most commonly used reference city in world clock and time conversion tools.
What is the UTC offset for SBT?
The UTC offset for SBT is UTC+11:00. This means local time in Solomon Islands is always 11 hours ahead of UTC, so 3:00 PM UTC converts to 2:00 AM SBT on the following day.
When does SBT change?
SBT does not change seasonally because the Solomon Islands do not observe daylight saving time. In 2026, there are no clock changes and no transition dates, so the offset stays fixed at UTC+11:00 from January through December.
Is SBT ahead of UTC or behind UTC?
SBT is ahead of UTC by 11 hours. That makes it one of the earlier time zones in the Asia-Pacific region, which is important when coordinating with Europe or the Americas because business hours in Solomon Islands often fall on the previous calendar date in those regions.
Is SBT the same as Australian Eastern Time?
Not always. SBT is always UTC+11, while Australian eastern time can be UTC+10 in standard time or UTC+11 in daylight time depending on the state and season; for example, Sydney matches SBT during daylight saving time but is one hour behind during standard time.
Does SBT have a daylight saving version?
No, there is no separate daylight saving version of SBT currently in use. The Solomon Islands keep the same civil time throughout the year, which simplifies recurring scheduling for regional operations, shipping timetables, and international project coordination.
