The problem is not in the accuracy of the transmitter or your
capability to receive it, but in the path between transmitter
and receiver.
I have both DCF77 and GPS receivers connected and there is a very
clearly visible change in the relative offsets between those
over a day/night cycle.  This is of ms order of magnitude.
