Who has measured the time of day from every location on the earth during equinox?
No one Tom. Care to try it and report your findings? See you in a few lifetimes.
I could ask you to do that to prove that there isn't a 12 hour day and 12 hour night at every location on Earth.
The only thing you have to do is find one location, but you won't, because there isn't one.
But of course, even if you did, you never post any data, just words.
Now, how about you fix your theory. The seasons are still broken.
