Of course not. But religions make a great deal of dates or at any rate sequences of events. If it were just a matter for historians a major discrepancy would be a matter for red faces and mayvbe a damaged reputation but in a religious context it's far more serious. Imagine if someone had proven that Pontius Pilate was in Gaul all through Jesus's supposed time.
