Clock time and sun time in Rio Gallegos
A time zone is an agreement, and the sun does not follow it exactly. Río Gallegos, the largest city in this zone, lies at about 69.2° west. Each degree of longitude is worth four minutes, so by the sun alone its time would be about 4 hours 37 minutes behind UTC. The clock is set to UTC−3. The sun is therefore highest in the sky at about 1:37 pm by the clock, not at 12:00. The clock runs more than an hour ahead of the sun here, one of the wider gaps in the world. Mornings stay dark late by the clock and evenings stay light. Other places in the zone, to the east or west of Río Gallegos, see the sun peak a little earlier or later. Through the year the figure also drifts by up to a quarter of an hour either way.
How long the day is
Río Gallegos is about 51.6° south of the equator. On the longest day of the year, around 21 December, the sun is up for about 16 hours 40 minutes. On the shortest, around 21 June, for about 7 hours 48 minutes. That is a swing of about 8 hours 52 minutes between summer and winter, yet the clocks here stay the same all year.
