I was wondering whether you could convert every data point
(lat,lon,date,time) in both sets to some integer value, reflecting the
time and space marging/precision and then use intersection from
http://www.dfanning.com/tips/set_operations.html

If this would work, this doesn't find the closest point in B for each
A, but the overlapping points (overlapping margins). But so does your
code, so I guess that's what you want.
