If you move one clock very slowly away from the other, the error is minimised, perhaps even to a degree that allows for statistically significant measurements.

To cite the Wikipedia entry that one of the other commenters linked:

"The clocks can remain synchronized to an arbitrary accuracy by moving them sufficiently slowly. If it is taken that, if moved slowly, the clocks remain synchronized at all times, even when separated, this method can be used to synchronize two spatially separated clocks."

One-Way Speed of Light

And further down:

Unfortunately, if the one-way speed of light is anisotropic, the correct time dilation factor becomes {\displaystyle {\mathcal {T}}={\frac {1}{\gamma (1-\kappa v/c)}}}, with the anisotropy parameter κ between -1 and +1.[17] This introduces a new linear term, {\displaystyle \lim \_{\beta \to 0}{\mathcal {T}}=1+\kappa \beta +O(\beta ^{2})} (here {\displaystyle \beta =v/c}), meaning time dilation can no longer be ignored at small velocities, and slow clock-transport will fail to detect this anisotropy. Thus it is equivalent to Einstein synchronization.

Except if you continue reading beyond your Quote, it goes on to explain why that actually doesn't help.
