I try to use the Graphhopper Map-Matching. My GPX source file looks something like:
<?xml version="1.0" encoding="UTF-8"?><gpx xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.topografix.com/GPX/1/0" version="1.0" xsi:schemaLocation="http://www.topografix.com/GPX/1/0 http://www.topografix.com/GPX/1/0/gpx.xsd" creator="gpx.py -- https://github.com/tkrajina/gpxpy"><trk><name/><type/><desc/><trkseg>

</trkseg></trk></gpx>
Then i run:
./map-matching.sh action=import datasource=mypath/india.osm.pbf vehicle=car
./map-matching.sh action=match gpx=mypath/myfile.gpx
But the resulting gpx file lost all it's times.Either its taking current datetime or 1970-01-01T00:00:00Z.

My question is why its taking 1970-01-01T01:00:00Z or current datetime as start and it continues.why it doesn't take my input time and process it? Thanks in Advance.
