[Gpsbabel-misc] GPX resolution in milliseconds?

[Gerhard O. <ger...@gm...>]

Thanks for a very useful application.

Time in tracklogs allows down to millisecond resolution.

However, GPSBabel seem to only write whole seconds.
(I write "seem" as I use xcsv<-> conversion, that may remove the precision.)
Can this be changed?

The reason to why I am asking is that a track can have trackpoints
quite close. I use it to "apply" splittimes on an existing track. The
speed noise get very high. 1 second resolution when there are
trackpoints every 4 second gives a very noisy speed.
I believe that using second resolution time in GPX only gives GPS
receivers a bad reputation because of this.

This question is possibly mostly interesting for fitness. I have seen
Robert stating that "GPSBabel is not in the fitness business", but I
really would like if GPSBabel supported a standardized extension for
GPS-Fitness with stuff like heart rate and cadence. Currently all
applications use their own way to represent the data. (Garmin
extensions as a basis?)
