The smallest fraction of a second measured is of the order of 10-15 attoseconds

(10-15*10-18 seconds, or 10-15 quintillionths of a second).

According to the current understanding of the laws of physics, the smallest unit of time that can be measured is the Planck time which is approx 5.4*10-44 seconds.
