Clock is a period-2 oscillator found by Simon Norton in May 1970.[1]
Clock can also serve as a weak sparker - although the edge cells cannot birth new cells without being destroyed, they can be used to suppress cell birth by overpopulation, as seen in p124 lumps of muck hassler.
It serves as the logo of WinLifeSearch.

The clock is a part of a family of p2 oscillators that can be seen as stabilisations for the zebra stripes/chicken wire agar - such extensions may lose symmetry. The nextmost simplest oscillator in the family is cha cha.
The rotor of clock is a muttering moat and is identical to that of quad.
Clock is the sixth most common oscillator in Achim Flammenkamp's census, being somewhat less frequent than the pentadecathlon, but much rarer than the blinker, toad, beacon or pulsar. It is by far the rarest 6-bit object, being about 45 times rarer than the snake.[2] It is also the sixty-second most common object on Adam P. Goucher's Catagolue.[3]
In other rules
In outer-totalistic rules, clock can follow at least three different p2 cycles depending on the rule, which all have mod 1.
- In rules such as B4/S1 the inner two cells oscillate similarly to a duoplet in Seeds.
- In rules such as B3/S3, the outer cells oscillate (this being the sequence seen in Life).
- In rules such as B34/S, both of these evolutions take place simultaneously, causing it to evolve into an inverted version of itself and therefore making it a phoenix.
This gives three different p2 sequences:

|
| B3/S3 to B35678/S02345678 | B34/S to B345678/S0245678 | B4/S1 to B45678/S01245678 |
Further sequences are possible in non-totalistic rules; for instance, in B3j/S1, clock cycles with one phase of toad.
