−1 (although this deserves −4) because: 1. Unless you actually need them, all interrupts are disabled by default, with the sole exception of TIMER0_OVF, which is needed for time keeping. 2. The timing accuracy of the Arduinos is limited mainly by the quality of the resonator. 3. Interrupts do no affect the accuracy of millis() unless you manage to spend more than one millisecond at a time servicing them, in which case you have other problems... 4. Disabling interrupts with noInterrupts() will prevent millis() from keeping time at all!
