Wrench messaged do not include a Header field. Without a header, there is no timestamp information available with which to synchronise incoming messages.
You'll need to use a message with a Header, such as WrenchStamped.

Wrench messaged do not include a Header field. field (docs). Without a header, there is no timestamp information available with which to the TimeSynchronizer can synchronise incoming messages.messages. From the wiki page:
The
TimeSynchronizerfilter synchronizes incoming channels by the timestamps contained in their headers [..]
You'll need to use a message with a Header, such as WrenchStamped
what i do is just change the topic and the type of argument, but it is wrong somewhere
that is a good approach, but as most things are (almost statically) typed with topics (at least in C++), can lead to issues such as the one you encountered.
