What is the reason of using
CFTimeInterval instead of double in Objective C?

The actual type used might change from one platform to another, as
int did when CPUs transitioned from 32 to 64bits. Also, variables defined with the platform independent type could be considered more self descriptive - nobody will wonder if a CFTimeInterval variable is in hours, milliseconds, etc, because the type is documented to mean seconds.
