They just divide up seconds, into milli- micro- nano- etc. It's possible that the shortest interval of time is 10 to the -43 power seconds ... if time is discreet. Further details: The smallest measurable and meaningful unit of time is Planck time. In physics, this is equal to the time it takes for light to travel, in a vacuum, a distance of 1 Planck length. However, since most of us cannot relate to physics, the shortest unit of time is the Yoctosecond, which is one septillionth (short scale) of a second.
