One second is 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium-133 atom.
Then there is millisecond, microsecond, nanosecond, picosecond, femtosecond, attosecond, zeptosecond and yoctosecond.
After that, it is a Planck time.
Maybe when the technology develops, there will be more units after yoctosecond.
