The pages linked in the right-hand column contain lists of times that are of the same order of magnitude (power of ten). Rows in the table represent increasing powers of a thousand (3 orders of magnitude)
Note:
Planck time, the shortest physically meaningful amount of time, is approximately
5.4 x 10-44 s.
Orders of magnitude of other quantities: length, area, volume, mass
