ApproximateTimeSynchronizer publishes in_sync topics through the callback?
Hello everyone.
I am trying to synchronize topics with the use of message_filters and ApproximateTimeSynchronizer. I subscribe to the topics that I want to synchronize but when I examine them they don't seem to have the same timestamps. I think I am missing something.
My first impression was that ApproximateTimeSynchronizer just receives data through the subscribers and then republishes them with shared timestamps. But now I think that the Synchronizer just takes in data from the subscribers and filters them without republishing them and IF I wanted to republish them with shared timestamps or whatever then I should do that through the callback.
I would really like some feedback on how to work with this, thanks in advance!
