Hi!

The documentation stands that any pending operations will be cancelled, just like calling timer.cancel().

Have in mind that the handler for the cancelled operation will be called with error_code set to boost::asio::error::operation_aborted.

Best regards

Hi,

Is it necessary to call the timer.cancel() before timer.expires_from_now? I think it is not just unnecessary, it will be a bug to call the timer.cancel() before timer.expires_from_now, I think that will run the cancel if the previous timer is not expired, is it correct?

Thank you
