This stack overflow question should tell you why that's the preferred clock type for timing function execution.

In order to make usage fully concise (avoid repetition), we can use a template function and implement the idea proposed by 5gon12eder, in this comment which simply creates the time_sink object and uses template function type deduction to fill in the details.

As 5gon12eder points out, you must also ensure that you keep the return of make_time_sink in order to prevent time_sink's destructor from running early, since destructors are called at the "end of the full expression, for nameless temporaries" (source).
