I want to rotate this image which would be the hour image with the New York timetable; example if it is 2 p.m. in Paris in New York it should be 8 a.m. if facer does not take the negative + 6 p.m. so.
What would be the formula for having the right time while knowing that my image turns on itself at point x: 115 and at point y: 82 with which formula also would it turn on itself?

I would make another image for our Tokyo wheel but I think it will be the same except the rotation position of my image.

It’s perfect, it’s exactly the formula I was missing for New York, however, there is a 6 hour shift so the formula is:
(( #DK # -6) * 30) / 360 for New York and +7 instead of -6.

I got there but it was very complicated because in fact FACER has trouble with the - negative but it’s ok everything works thank you because I got there thanks to the basis of the formula that you gave me.
