    When drawing the diagram, the textbook shows that it starts off with a source node which is 0. However, I have encountered a question in a past paper which starts off immediately with the node 1. Any explanation?

    Thanks

    I don't think it matters too much to be honest, as long as it doesn't go from 0 to 2..

    It doesn't matter whether it is 0 or 1. It doesn't really need a number at all, they are just there as they may help with filling in the early event times.
