[OSM-talk] JOSM update / why does API return GPS points in descending order?

But they can't be too arbitrary since drawing lines in between the 
points would reveal a completely chaotic picture otherwise. I think 
David Earl is right about sorting by timestamp since this is what's in 
the API source:

points = Tracepoint.find_by_area(min_lat, min_lon, max_lat, max_lon, 
:offset => offset, :limit => TRACEPOINTS_PER_PAGE, :order => "timestamp 
DESC" )

... and the "DESC" nicely explains the observation that all arrows are 
in the wrong direction! I wonder why it is there. TomH?
