The timestamp returned is "2015-10-11T12:04:49.108221"

I put data using tools/make_test_data, maybe that's a cause, IDK.

    Correct the timestamp type when make test samples data

    When recording samples to database, the timestamp should be
    datetime.datetime type, but in make_test_data.py, the timestamp
    will be transformed to iso format with unicode type.
