Constructor.
basic_waitable_timer( const executor_type & ex);
This constructor creates a timer without setting an expiry time. The
expires_at()
or expires_after()
functions must be called to set an expiry time before the timer can be
waited on.
The I/O executor that the timer will use, by default, to dispatch handlers for any asynchronous operations performed on the timer.
