Furthermore, the elapsed time evaluating an expression (even one with no other apparent side effects), is sometimes essential to the correct operation of a system, as behaviour in time is easily visible from outside the system by other parts of the system with which it interacts, and might even be regarded as the ''primary'' effect such as when performing [[Benchmark (computing)|benchmark testing]].

It depends on the particular programming language specification whether an expression with no apparentabstract side effects can [[Program optimization|legally be eliminated]] from the execution path by the processing environment in which the expression is evaluated.
