Hello, I want to contribute to OSM with some GPS tracks because is very easy for me. But I’m concerned about privacy and I would like to change the timestamps. I want to preserve the timestamps (better said, the relation between timestamps) but changing that date and time. I can do it editing manually the text in the GPX file but I’m looking for a simple automatic way of doing this.
For example, having these timestamps:
05/04/2018 12:41:35, 05/04/2018 12:41:40, 05/04/2018 12:41:45
I would like to get something like this:
08/02/2018 21:17:15, 08/02/2018 21:17:20, 08/02/2018 21:17:25
Is another date, another time, but the difference of timestamps between each other remains the same. So timestamp information is not lost.
Could you extend your answer a little more? I downloaded Gpsbabel and import the original track on it but the list of available formats I don’t see GPX, also I don’t know how to do the desired changes in the “translation”.
