I created a layer of 10,000 random points. Using timezonefinder to look up each point took 44 seconds. I tried using *Vector->Geoprocessing Tools->Intersection...* to find the time zones for each of the points and it took over 4 minutes. Is there a better way to locate which polygon a point is

It was suggested to me that the default coordinate order in the Lat Lon Tools plugin for coordinate capture and zoom-to tools should be "longitude, latitude" or "X, Y". Originally, Lat Lon Tools was designed to work with on-line maps which are generally "latitude, longitude" order. You can always
