Clock time and sun time in Pontianak
A time zone is an agreement, and the sun does not follow it exactly. Pontianak, the largest city in this zone, lies at about 109.3° east. Each degree of longitude is worth four minutes, so by the sun alone its time would be about 7 hours 17 minutes ahead of UTC. The clock is set to UTC+7. The sun is therefore highest in the sky at about 11:43 am by the clock, not at 12:00. The clock runs a little behind the sun here, so mornings are light early and evenings darken sooner. Other places in the zone, to the east or west of Pontianak, 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
Pontianak is about 0° south of the equator. On the longest day of the year, around 21 December, the sun is up for about 12 hours 7 minutes. On the shortest, around 21 June, for about 12 hours 7 minutes. So close to the equator the day is almost the same length all year. Moving the clocks would gain nothing, and Pontianak does not do it.
