Thanks, that's it, now how do I filter only successful timer triggers?
I added the following line to on_time_out():

cout << "Error #" << error << ": " << error.message() << endl;
 
And successful call resulted the following output:
Error #system:0: The operation completed successfully

but I failed to find the correct error_code value I've tried:

if(error == boost::asio::error::success)
and
if(error == boost::system::error::success)

but non of them is valid, what is the valid success condition?
thanks again,
Peleg
