In fact, the position of all objects changes slightly over time and a 
coordinate should be a vector indicating a position and a (presently 
best value of) direction and speed of drift.
The Greenwich meridian is presently 102m west away of the zero latitude 
of a GPS and it continues to drift.
See Greenwich Meridian <https://www.openstreetmap.org/way/268533450>  
which is now 0.0014864° W by its nodes (which should have the same value 

All the best,
