title: Accuracy of GPS Timestamp in depending on position accuracy
body: <p>In need to exploit in my application time obtained from GPS. I need position and I need to know a time stamp which I can globally trust. </p>
  
  <p>I'm getting information how accurate my position is, for instance 5m, 100m etc. 
  But I would like to know how accurate it my timestamp depending on position accuracy. Of course I know that the accuracy of the position is correlated with accuracy of the timestamp (this is basic idea of gsp), but I would like know what error of the timestamp (in miliseconds) should I expect when I'm getting position with  accuracy 5m ,50m, 100m etc. Is there easy way to calculate that?</p>
