passing elapsed time instead of real timestamp to the GeomagneticField constructor

[ftabashir]

Last parameter of GeomagneticField constructor is timeMillis. Here is the documentation of this parameter:

Time at which to evaluate the declination, in milliseconds
since January 1, 1970. (approximate is fine -- the declination
changes very slowly).

In KalmanLocationService the timestamp which is passed to GeomagneticField is calculated like this:

timeStamp = Utils.nano2milli(location.getElapsedRealtimeNanos());

As you see Location.getElapsedRealtimeNanos is used which its value is nanoseconds since last device boot (instead of milliseconds since January 1, 1970)
Shouldn't it be Location.getTime()?

So, this is an error and we should use unix timestamp instead of Location.getElapsedRealtimeNanos. Does Location.getTime() do what we want? We will change it then
