The timezone NCT in New Caledonia

Timezones are always computed by their difference to UTC, the "Universal Time Coordinated". In New Caledonia exists only a single tonezone at UTC+11. E.g. New York is currently at UTC-5 in Eastern Time, so the time difference between New York and New Caledonia is 16 hours.
New Caledonia has no time difference between summer and winter. A daylight saving time doesn't exist.

New Caledonia has an east-west extension of 4.2 degrees of longitude. Given the country's location in Melanesia, this corresponds to about 440 kilometers. With such a small extent the course of the sun at different positions in the country hardly matters. The position of the sun in the west of the country deviates from that in the east only about 17 minutes. This means the sun rises and sets 17 minutes later in the west than in the east.

No more daylight saving time in New Caledonia

Due to the sun's orbit around the equator, the days are longer in summer (November to February in the southern hemisphere). Countries that switch to daylight saving time in the summer months align the daylight phase with the human rhythm. Unused bright morning hours are thus shifted into the evening (more information on daylight saving time here).
Due to the relative proximity to the equator, the impact in New Caledonia is not particularly large. Nouméa is only 2,500 km from the equator. A day in midsummer would then not last from 05:06 to 18:38, but from 06:06 to 19:38. The effect would be quite noticeable in the evening, but the sun rising later in the morning falls at a time when many people are already awake. Thus, in 1997, the decision was made to finally abandon daylight saving time in New Caledonia.
