csv - How do I convert a set of latitude/longitude coordinates with timestamps to a GPX tracklog?

Converting tracks from a GPX track to a CSV table or some other format is relatively easy, but I'm looking to go the other way. I have a table of point locations logged with a handheld GPS, with timestamps. I need to convert them to a GPX file with a tracklog containing those points so they can be used with some other software to geotag some photos. I can convert them to GPX waypoints easily enough using QGIS/GDAL, but not to a GPX tracklog, the timestamps are lost.

Here's the header of my CSV:

Lon,Lat,Altitude,NewTrack,TimeStamp,Datum,InternalTime

Answer

GPS Visualizer will pass your time stamps to gpx format.

Using the online tools will preserve your timestamp in the .csv file.

Convert a GPS file to plain text or GPX

This form reads a tracklog or waypoint file (in a recognized format) or plain-text tabular data, and converts it to an easy-to-read tab-delimited or CSV text file, or to a GPX file.
