Fine, that it works now.

Lat, long are doubles that will be multiplied by 10000000.0 and rounded (and shifted to get a unsigned integer number). I haven't calculated it myself but this is a common trick fromt he OSM world and is saif to have still enough precision for real world position. Note that the position error of the dvice is normally higher.

I currently use the default, but liblocation allows time precision of 1,2, 5, 10, 20, 30, 60, 120 seconds. I can add this to the TODO list.

Yes time is already stored in the internal file format and thus can be added to the KML output. Do you have a link to a concrete example for how time is stored in KML?

Other than that, thanks for making it available to us
No problem with adding valid feature requests to the TODO list ;-) I think the time stuff should be the easiest one to add.
