Fix GPX paths exported from Strava by restoring the timestamp

strava_to_doarama.py

#!/usr/bin/env python

"""
For some reason, Strava lets you export the GPX of another athletes but removes
the timestamps, presumably so that you can't "steal" their paths.

This script adds fake timestamps to these GPX files, so that you see the
overview of the run in other services like doarama for instance.

Technically, the script adds a timstamp after the </ele> tag, +1s at each point:

    </ele>
    <time>2016-01-01T00:00:31</time>
