title: Garmin .fit file timestamp
body: <p>I'm hoping someone can put me on the right path.  I'm developing an embedded project that will use the fitSDK.  One of the fields in the .fit file is the timestamp.  </p>
  
  <p>The only valid timestamp for the fit file is a uint32_t that is seconds since UTC 00:00 Dec 31 1989.</p>
  
  <p>Since they aren't using epoch time, this could turn into something ugly....unless I'm totally overlooking something (very possible).</p>
  
  <p>code snippets and or links to good information are welcome.</p>
