"But, at the risk of trivializing, what I actually find even stranger is 
that at the core, geo is really about two numbers (lat,long) or 3 if you want to add altitude (and yes, even a polygon is just a container of

into this nowadays."

I'm pretty sure we've had this "conversation" before ... I won, don't you remember ? :-) ... for anything less than a day you need a Time Zone too or plain old differential equations will knock you out of sync - they are not semantics either.  Sometimes you have to go to great lengths to satisfy volatility addicts and short attention spans ...
