Hello,

Working with 0.8.1

date_range works nicely, I am using the technique to reduce sparse GPS measurements to a fixed time step.

procedure:
step 1: create date_range ("10S"), all datetime within a single day (input from gpx)
step 2: outer join with original data
step 3: interpolate the locations

Everything works fine, .to_string() results in results as expected.

When I export the result to_csv(), the date_range object is exported with the correct datetime, but the date part is reduced to to january 1970. How is this possible?

Can somebody get me on the road again?
