Where are you getting that information from? My understanding was that all three pitot tubes froze almost simultaneously in a matter of seconds, thus making the time discrepancy somewhat irrelevant.
The point I was trying to make was that the instinctive reactions of the PF were not in response to any specific warning, but a panic reaction to the situation - attitude, turbulence and aural warnings.
