Hi Michael,
My tech once told me that +/- 1/6 of a stop is considered accurate for a spring actuated shutter. So at 1 second somewhere between .84sec and 1.16sec. He also stated that if it's out more than a 1/3 of a stop it's time for a service. Now a days an electronic shutter is probably 1% or less.
