What is the benefit of the global clock, in that case?

[CuriouslyC]

It gives you a single "correct" order of events, and a single present state.

It gives to whom a single correct order of events and present state? Not to me. Only to "God", an entity external to the system.

Which is fine if you are a God (or programmer) building a simulation, but has no objective meaning to anyone inside.
