run the given code periodically at time `first`, `first+p`, `first+p*2`, etc. until this clock has reached `last`.
In case any of the instants `first`, `first+p`, `first+p*2`, etc. happen to be in the past when this is called or after the previous execution of code, respectively, do not run code for that instant.
return the number of times the code was run
