Common sense was warning your idiot guru.

 The notion of "local proper time" looks a bit like a tautology.
Saying: "the local proper time of this phenomenon is 15 microseconds" is like saying this swallow is a swallow.
There is a proper time, and an improper time. But there is no local proper time and delocalized proper time.
What happens is just a different notion of time by change of observer in relativity.
This phenomenon, which lasts 15 microseconds, will have a different duration if it is measured by a different observer. But proper time itself is invariant, and is only local in any case.
 The correct relativistic  equation is :
t'=t.sqrt(1+cosµ.v/c)/sqrt(1-v²/c²)
 And not t'=t.
 And not t'=t/sqrt(1-v²/c²)
