What? The amount before/after noon will certainly depend on longitude aka
position within the time zone.  The fluctuation will depend on latitude,
since I imagine that at the equator chatzos does not fluctuate, since
there is no summer/winter.

What do you mean then?  (Or correct me where I'm wrong.)
