    public class TimeRange 
    Public Class TimeRange 
    TimeRange contains two properties Start and End which defines an extent of time. Either property can be set to null. When Start is null it means the time range begins infinite in the past and when End is null this means it ends infinite in the future. This is useful for example when setting the MapView.Time property to show all time before a given date, all time after a given date or to just show all time.
    Step forward in time by 1 month
    public void StepMapTime()
      //Get the active view
      MapView mapView = MapView.Active;
      if (mapView == null)
      //Step current map time forward by 1 month
      TimeDelta timeDelta = new TimeDelta(1, TimeUnit.Months);
      mapView.Time = mapView.Time.Offset(timeDelta);
    Interpolate Time
    public Task<List<TimeRange>> GetInterpolatedMapTimes()
      //Return the collection representing the map time for each frame in animation.
      return QueuedTask.Run(() =>
        var mapView = MapView.Active;
        if (mapView != null || mapView.Animation == null)
          return null;
        var animation = mapView.Map.Animation;
        var timeRanges = new List<TimeRange>();
        //We will use ticks here rather than milliseconds to get the highest precision possible.
        var ticksPerFrame = Convert.ToInt64(animation.Duration.Ticks / (animation.NumberOfFrames - 1));
        for (int i = 0; i < animation.NumberOfFrames; i++)
          var time = TimeSpan.FromTicks(i * ticksPerFrame);
          //Because of rounding for ticks the last calculated time may be greating than the duration.
          if (time > animation.Duration)
            time = animation.Duration;
        return timeRanges;
