Hi Richard,
above all thanks for your reply and your work on potlatch.
I'll use this time schema in the future, but i have a doubt: if i upload 
several gpx of the same area both timed with "epoch +x", they may appear 
mixed? the same may happen if several users not faking time tracks upload 
traces taked in the same hours (imagine a mapping party) ?
If it is so the db should be modified and some field should be added (a serial 
big int?).
Howewer, returning to the original issue, in the mean time may you implement 
an option in potlatch to hide lines between points as done in other editors?

As a general question, and as it's not documented yet on the wiki, are the 
rest api to get trackpoints unchanged between 0.3 and 0.4? why potlatch 
use /api/4.0/swf/trackpoints instead of /api/4.0/trackpoints ?

best regards
