    When your watch (which you set correctly before you left home) reads 12:00 noon.

    If only it were that simple!

    How about 4 people meeting at the South Pole.
    Coming from 0, 90, 180 and 270 degrees longitude.
    Their watches wont agree.
    Sop what time is it when they meet ???

    It is that simple. Most of the research teams working at the South Pole follow
    the time zone of their home country or the closest point in the inhabited world.

    Since all time zones converge at the pole, the four people meeting would have to
    agree on one time zone (in the spirit of science and fellowship).

    Of course.

    Where in the tropical zone is the Sun directly overhead more than once during the solar year?

    Everywhere between the Tropic of Capricorn and the Tropic of Cancer gets the sun overhead twice a year!

    What meal would they have? Breakfast, lunch, dinner or supper?

    A bit of googling found that "officially" the Antarctic is on UTC but in
    practice uses NZ time as that is typically where they are supplied from.

    But just once a year for observers on the two tropic circles at the solstices (June and December).

    Yes of course - when Apollo turns his steeds around.
