Can TimeSynchronizer be made to react to a non-associated message?

Using a TimeSynchronizer of two topics, can my application be notified when a message of either topic gets dropped because no corresponding message of the other topic was received?

Quick comment: you should be able to use registerDropCallback(..) for this.

Thanks, that's helpful, but I can't see which topic's message was dropped, can I?

I don't believe you can, no.

Hi, I see that registerDropCallback() works only for synchronizers with ExactTime policy only. Do you know if the same behavior is achievable with ApproximateTime policy, too? the method does not exist in this case.

Thank you
