What time zone do researchers at the South Pole use? Everywhere else, barring the adjustments for daylight savings, boundaries, approximations, etc, noon is supposed to be when the sun is at its zenith (that’s why they’re called meridians).
All the meridians meet at the South Pole, though; but obviously the South Pole has a day and night. So when does the sun’s zenith at the south pole take place? And what time zone is it considered a part of?
I presume the whole region around the south pole is considered part of one time zone - otherwise you could rapidly change hours of the day (not to mention dates) by taking a quick jog around the pole.
Also, since the date line touches the south pole, what date is it?
They generally use the same time zone as their home country or research institution. New Zealand’s time zone is also commonly used, since that’s the source of all incoming/outgoing flights.
