The Indonesia times are still subject to the solar noon transit time fluctuation,
Which all over the world, affects sunrise/sunset times by up to 29 minutes "November to February" and 11 minutes of fluctuation (May thru early August)
It's called "equation of time"
Mean solar day and actual solar days are not the same due to axial tilt and earth's elliptical orbit around the sun
This means even in Indonesia, sun will set 30 minutes later on February 14th when compared to November 5th.
Yes. Sunrise/set times are so important here, as the Muslims' (about 88% of Indonesians) prayer times, so we noticed the sunrise/set times.
But, here, a 10min difference is quite big for Indonesian.
I think, DST should be applied in May - August, not March - October.
In Americas, DST even starts in the last 2 week of winter.. It is weird having pitch dark at 7am.
