Re: [Jason-users] Create a timer based on seconds in Cartago

Hi Jomi,
When I pause the agent execution on the container, everything stops, but
another thread which created using a session does not stop. I would like to
capture the "Pause" of the agents runtime to pause the other thread. But i
think your idea is also applicable.
Thank you.
Best regards.
