get_queue_data() provides "0" for the agent departure time.

Hi

In very minor cases the departure time for an agent is "0", where on the other hand the service start time is ok. This raises issue when calculating the service time, which results in a negative value. I also have the screenshot attached:

The problem happens in the end of the simulation time. In my opinion because not all the agents manage to leave the network before the simulation finishes. Is there a way (e.g. a trigger) to fix this minor issue?

Oh I think this issue is the same to the one reported here #69. If so, I think this is actually correct behavior. If it is any help, it is probably safe to replace all zeros in that column with NaN so that things can be aggregated nicely.

Agents that have arrived but not departed have a departure time of zero when queueing-tool outputs statistics. I now think that better behavior would be to have a departure time of np.nan, or better yet, have the default value be customizable.

But to answer your query, there is no way to change it in queueing-tool at the moment.

Thank you for your quick answer. I think using NaN or np.nan is a better choice for now to avoid confusions when calculating or sorting information.
