Sure, no doubt. My point wasn't really about the particularities. It was around the mistaken idea that I see sometimes where people believe that TrueTime allows for synchronized global writes without any need for consensus.

The speed of light in vacuum is a hard upper limit. Most signal paths will be dominated by fibre optics (about 70% of C) and switching (adding more delay).

But, yes TrueTime will not magically allow data to propagate at faster-than-light speeds.
