+<para>
+Trackpoint timestamps between the first and last points are calculated such that track is travelled at equal speed.
+This is mostly useful when tracks don't have timestamps and you wish to recreate your trip (e.g. you've forgotten to turn on your GPS or the batteries have run out)
+Thus edit the first and last trackpoints to set the approximate times of your trip and then use this to give approximate times along the track.
+When used on tracks with timestamps this will overwrite the existing timestamps.
