Consider that they have a crystal as a fly-wheel oscillator, so if that
does a frequency jump, it will show, but be tracked in. If the
oscillator does a phase-jump, it will show too. If there is other issues
in the tracking-loop, it will show.

So, yes.

This is true for any passive atomic clock. I'm sure active hydrogen
masers can have similar effects.

Cheers,
Magnus
