Clock time and sun time in Azores
A time zone is an agreement, and the sun does not follow it exactly. Ponta Delgada, the largest city in this zone, lies at about 25.7° west. Each degree of longitude is worth four minutes, so by the sun alone its time would be about 1 hour 43 minutes behind UTC. The clock is set to UTC−1. The sun is therefore highest in the sky at about 12:43 pm by the clock on standard time, and at about 1:43 pm while the clocks are moved (UTC). The clock runs ahead of the sun here, which means later sunrises and lighter evenings than the map alone would give. Other places in the zone, to the east or west of Ponta Delgada, 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
Ponta Delgada is about 37.7° north of the equator. On the longest day of the year, around 21 June, the sun is up for about 14 hours 47 minutes. On the shortest, around 21 December, for about 9 hours 33 minutes. That swing of about 5 hours 14 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.
