Clock time and sun time in Nuuk
A time zone is an agreement, and the sun does not follow it exactly. Nuuk, the largest city in this zone, lies at about 51.7° west. Each degree of longitude is worth four minutes, so by the sun alone its time would be about 3 hours 27 minutes behind UTC. The clock is set to UTC−2. The sun is therefore highest in the sky at about 1:27 pm by the clock on standard time, and at about 2:27 pm while the clocks are moved (UTC−1). 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 Nuuk, 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
Nuuk is about 64.2° north of the equator. On the longest day of the year, around 21 June, the sun is up for about 21 hours 11 minutes. On the shortest, around 21 December, for about 4 hours 6 minutes. That swing of about 17 hours 5 minutes between summer and winter is the reason clocks are moved here: the extra summer daylight is shifted from the early morning to the evening.
