11842	Allow time offsets with decimal point	skorbut	bastiK	"I would like to be able to enter a time offset for geotagging a photo as a number with decimal point (mathematically speaking: as a rational number). I would then expect that the calculated position is interpolated linearly between the previous and the next point in the GPX track.

Currently, when geotagging a photo the time offset must be given as an integer number. Otherwise the error message `Error while parsing offset.Expected format: number` is given.

A calculation: When driving with a speed of 120 km/h (about 33 m/s) the error introduced by this kind of rounding error may be up to over 16 m. (That is the case when the correct position would lie exactly in the middle of two points of the GPX track.)
