I'm having trouble relating this comment to the referenced paper [1], which seems to be explicit that its impossiblity result does not apply when synchronised clocks are available.

For example, on page 375: “Crucial to our proof is that processing is completely asynchronous; that is, we make no assumptions about the relative speeds of processes or about the delay time in delivering a message. We also assume that processes do not have access to synchronized clocks, so algorithms based on time-outs, for example, cannot be used.”

You mean the OP's comment or mine? I agree with you if you mean the OP's comment. Though your quote refers to synchronized clocks. I dont think OP is referring to synchronized clocks, though your point that Lynch et al does not rely on timeouts is what Im getting at.
