What is the magnitude of the delta that you observe? What does "show clock verbose" say about the state of clock-rate convergence? Is a deus ex machina (e.g. NTP) involved?

Is this expected to happen ? (presumably because of the implementation which tries to align the times in workers ?) I have an implementation which is extremely sensitive to time at microsecond level and depends on the the vlib_time_now only increasing monotonically across calls individually in the workers (or remain the same but never decrease) on a per worker basis even if the times within the workers are not synchronized.
