UTC and NUT examples

These examples always use UTC (UTC+0) and NUT (UTC-11). They stay the same when you change the date or time above. The selected conversion may differ when daylight saving time applies.

UTC is 11 hours ahead of NUT.

How the time difference changes

UTC is 11 hours ahead of NUT year-round.

Working hours of 9:00 am to 5:00 pm in UTC correspond to 10:00 pm (previous day) to 6:00 am in NUT.Working hours of 09:00 to 17:00 in UTC correspond to 22:00 (previous day) to 06:00 in NUT.

Compare UTC time with NUT time, including current local time, UTC offsets, time difference, daylight saving changes, working hours, and shareable meeting times.

UTC to NUT call time
Best time for a conference call or a meeting is between 6pm-7pm18:00-19:00 in UTC which corresponds to 7am-8am07:00-08:00 in NUT. Their 9am–5pm09:00–17:00 working hours do not overlap; this is a suggested compromise.

Coordinated Universal Time

Offset: UTC is the same as Greenwich Mean Time (GMT).

Coordinated Universal Time (UTC) is the world time standard that regulates clocks and time. It is the successor to Greenwich Mean Time (GMT). For casual use, UTC is the same as GMT, but UTC is the standard the scientific community uses.
UTC has been the time standard commonly used across the world since 1972. It is used in many technical fields, such as aviation and meteorology, and to synchronize time across internet networks.

Today some of the lighter areas are on UTC+1 (British Summer Time, Irish Standard Time, WEST).

Niue Time

Offset: NUT is 11 hours behind Greenwich Mean Time (GMT).

Countries using this time zone: Niue

Principal Cities: The largest city in the NUT time zone is Alofi in Niue, with about 624 people.

Daylight Saving: Clocks in Niue Time (NUT) do not change for daylight saving time, so NUT stays the same throughout the year. Other time zones may set clocks forward in summer and back in winter; see upcoming clock changes worldwide.
