I think that's a different issue. That adds jitter to measuring how long something takes. It doesn't add jitter to what-time-is-it-now, at least if you are somewhat flexible on what you mean by "now". How-long jitter can be filtered out or averaged, depending upon what you want. It's a lot harder to keep accurate time if your basic clock changes frequency, say due to temperature. -- These are my opinions, not necessarily my employer's.
