[OSM-newbies] accessing time stamps from GPX traces in Potlatch?

[Ed Hillsman]

Hi,

When using Potlatch to map a way from a GPX trace, is it possible to  
access the time data for individual points or, better still, the  
speed? When cycling for mapping, I stop along the way and photograph  
points of interest to record features (water, information, benches)  
for later tagging. My GPS unit does not have a function for recording  
waypoints, so if there is tree cover, as on a shared-use bicycle path,  
I can't always tell where to locate the POI by looking at the trace  
and Yahoo imagery alone. If I could retrieve the times of the trace  
points, I could look for gaps where I stopped to take the photos.  
Speed, of course, would be better. I don't know if this is available  
in JOSM, but even if it is, it would not be a good option, because I  
have never been able to get the Yahoo images to display with enough  
resolution (meaning, comparable to the way they display in Potlatch)  
to make it reliable for mapping.
