An attosecond is one quintillionth (10 to the power of minus 18) of a second.

As of 2006, the smallest unit of time that was directly measured was on the order of 1 attosecond (10−18 s), or about 1026 Planck times.

In physics, the Planck time, (tP), is the unit of time in the system of natural units known as Planck units. It is the time required for light to travel, in a vacuum, a distance of 1 Planck length. The unit is named after Max Planck, who was the first to propose it.
