I&#x27;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.<p>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.”<p>1. <a href="http:&#x2F;&#x2F;www.cs.princeton.edu&#x2F;courses&#x2F;archive&#x2F;fall07&#x2F;cos518&#x2F;papers&#x2F;flp.pdf" rel="nofollow">http:&#x2F;&#x2F;www.cs.princeton.edu&#x2F;courses&#x2F;archive&#x2F;fall07&#x2F;cos518&#x2F;pa...</a>
