In JOSM you can filter the loaded GPX tracks by date. In the layer list, right-click the GPX data,
select the funnel icon "choose visible tracks". It provides you with a slider mode to select a
specific from-to date range. Very useful when the road layout has changed, e.g. a roundabout been built.
(in this context, the InfoMode plugin provides you further information about tracks and trackpoints interactively.)
