I have questions about sundials, timezones and the tilt/obliquity of the globe:
-If the earth is tilted, then why aren’t time zones on a map skew?
(on the picture below, in June, it’s day in Canada and night in Peru at the same time)
-Can the gnonom of a sundial point to the 12 at noon in spring, looking at this picture below?
I decided to start a new topic to discuss the working of time, orbit and (types of) sundials, if that’s ok (maybe I overlooked an existing topic).
