The timezone TFT in French Antarctic LandsTimezones are always computed by their difference to UTC, the "Universal Time Coordinated". In French Southern and Antarctic Lands there is only a single tonezone at UTC+5. For example, New York is currently at UTC-5 in Eastern Time, so the time difference between New York and French Southern and Antarctic Lands is 10 hours.
French Southern and Antarctic Lands has no time difference between summer and winter. A daylight saving time doesn't exist.

The French Southern and Antarctic Time also applies in Heard and McDonald.
No daylight saving time in French Southern and Antarctic LandsDue 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 its distance from the equator, the impact would be significant in French Southern and Antarctic Lands. Port-aux-Français is located 5,500 km from the equator. A day in midsummer would then not last from 04:07 to 20:27, but from 05:07 to 21:27. Nevertheless, French Southern and Antarctic Lands has never introduced daylight saving time.
