Expose underlying clock in CThreadInterrupt

Overloading sleep_for is not needed, as

* seconds and minutes can be converted to milliseconds by the compiler,
  not needing a duration_cast
* std::condition_variable::wait_for will convert milliseconds to the
  duration type of the underlying clock

So simply expose the clock.
