  - shiftedBy
```
public AbsolutePVCoordinates shiftedBy(double dt)
```
    Get a time-shifted state.
    The state can be slightly shifted to close dates. This shift is based on a simple Taylor expansion. It is not intended as a replacement for proper orbit propagation (it is not even Keplerian!) but should be sufficient for either small time shifts or coarse accuracy.
    
    Specified by:
    
    shiftedBy in interface TimeShiftable<ShiftablePVCoordinatesHolder<AbsolutePVCoordinates>>
    
    Parameters:
    
    dt - time shift in seconds
    
    Returns:
    
    a new state, shifted with respect to the instance (which is immutable)
  - shiftedBy
```
public AbsolutePVCoordinates shiftedBy(TimeOffset dt)
```
    Get a time-shifted state.
    The state can be slightly shifted to close dates. This shift is based on a simple Taylor expansion. It is not intended as a replacement for proper orbit propagation (it is not even Keplerian!) but should be sufficient for either small time shifts or coarse accuracy.
    
    Specified by:
    
    shiftedBy in interface TimeShiftable<ShiftablePVCoordinatesHolder<AbsolutePVCoordinates>>
    
    Parameters:
    
    dt - time shift in seconds

    Create a local provider using simply Taylor expansion through shiftedBy(double).
