At a 1ps level of interest, that is not a well-founded expectation.

In particular look out for power-supply variations, which will transpose the trigger point for your "digital" clock-signals.

PS: Do not ignore mechanics either: At the speed of light 1ps takes you only 0.3mm.

Never attribute to malice what can adequately be explained by incompetence.
