In what direction is time in by default? #71

Hello, This isn't an issue, but more of a question. I tried using this, but I quickly found out that the direction of the arrows of fermions were messed up, if time was flowing upward on the y axis. Can you please let me know in which direction time is flowing by default, and if there is a way to change this?

Also, is there a way to add an arrow in the diagram that shows the direction of time?
