Clock time and sun time in Northern Mariana Islands
A time zone is an agreement, and the sun does not follow it exactly. Saipan, the largest city in this zone, lies at about 145.8° east. Each degree of longitude is worth four minutes, so by the sun alone its time would be about 9 hours 43 minutes ahead of UTC. The clock is set to UTC+10. The sun is therefore highest in the sky at about 12:17 pm by the clock, not at 12:00. 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 Saipan, 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
Saipan is about 15.2° north of the equator. On the longest day of the year, around 21 June, the sun is up for about 13 hours 2 minutes. On the shortest, around 21 December, for about 11 hours 13 minutes. The difference between summer and winter is about 1 hour 48 minutes, and the clocks stay the same all year.
