Time zone in Antarctica

Dumont-d'Urville Time (DDUT)

The differences between time zones to each other are always specified in relation to the "Universal Time Coordinated" (UTC), the time on the prime meridian (zero longitude). Phoenix, for example, is on the 122nd degree of longitude west and thus in the UTC-7 time zone. Dumont-d'Urville Time is consistent with UTC +10.

The Dumont-d'Urville Time does not have an associated daylight saving time.

The Dumont-d'Urville Time applies only to some parts of Antarctica.

Further Countries in the same timezone of UTC +10

Although the timezone is named "Dumont-d'Urville Time", it is mostly for politcal reasons. It simply means that, e.g., the beginning and ending of daylight savings time always apply here uniformly. There are some other countries, in which the clock strikes the same hour. These countries have the same temporal distance to UTC (Universal Time Coordinated).
