I’m not well versed in this field but if you take GPS using time as one of its parameters I could imagine being able to pinpoint the location of an atom from space to be one avenue of an endgame in making time so precise we would lose less than a Planck second in time over that period. That being said I don’t even know if time is the bottleneck for accurate GPS coordinates.
