Errr.. is that so?

We define time as "something" that happens/elapses between two events, one happening at the "observed" object (particle) and "observer" (affected particle).

I think we need at least two particles (observer is the reference) to be able to measure time (to determine if the event associated with object happened before or after the event(s) happening on the observer.
