GPSBabel supports data filtering. Data filters are invoked from the command
-x track,move=+1h,pack,title="ACTIVE LOG" \
-o gpx -F out.gpx
-START / STOP
+ START / STOP
Filter tracks against time borders. All points outside this range will be
dropped. The date-time paramters have to be in form of YYYYMMDDHHMMSS; but
gpsbabel -t -i gpx -f in.gpx -x track,pack,title="ACTIVE LOG" \
-o gpx -F out.gpx
-SPLIT
+ SPLIT
The input track will be split into several tracks depending on date of track
points. If there is more than one track, use the pack option before before
-x track,pack,split=4h,title="LOG # %c" \
-o gpx -F out.gpx
-MERGE
+ MERGE
Merge puts all track points into one single track and sort them by time.
Points with identical time stamp will be dropped !!!
