OK, since...
2) If someone asks about say, sunrise times, right now I have absolutely no motivation to answer it. Partly because the answer is already there and the people asking should know how to use the search function by now. However I would make the effort to do the subject again if it wasn't there already, discussed in every manner possible.
...getting the times from the web is OK, I will fill in the times by myself
At what time, on 21st March are the following events happening? Please use UTC times.
Irkutsk sunset: 11:18
Ulanbaatar sunset: 11:07
Chengdu sunset: 11:16
Singapore sunset: 11:15
Perth sunset: 10:26
New York City sunrise: 10:57
Port au Prince sunrise: 10:52
Bogota sunrise: 11:00
Lima sunrise: 11:12
Santiago de Chile sunrise: 10:47
Security question: is the sun shining during either of those events in:
London? Yes
Tripoli? Yes
Cape Town? Yes
I actually expected 11:00 UTC
Perth aside, because it's really significantly further east, all times divert by less than +- 20 minutes.
This proves that the Equinox day/night map I uploaded is accurate, and the spotlight theory needs to be revised.
