 FIT or Flexible and Interoperable Data Transfer is a file format used for GPS tracks and routes. It is used by newer Garmin fitness GPS devices, including the Edge and Forerunner series, which are popular with cyclists and runners.

-####"Fix" the Data
+#### "Fix" the Data
 FIT files have been observed where some data points are missing for one sensor (e.g. cadence/foot pod), where information has been collected for other sensors (e.g. heart rate) at the same instant. The cause is unknown and typically only a relatively small number of data points are missing. Fixing the issue is probably unnecessary, as each datum is indexed using a timestamp. However, it may be important for your project to have the exact same number of data points for each type of data.

 Unix time is the number of seconds since **UTC 00:00:00 Jan 01 1970**, however the FIT standard specifies that timestamps (i.e. fields of type date_time and local_date_time) represent seconds since **UTC 00:00:00 Dec 31 1989**.
