Hi Graham, all.
If we associate the time to the process execution, it does not necessary
mean that
the process execution generated the resource at a specific time. In fact,
the process
execution could continue once the resource has been generated...

However, I agree with you that we should focus first in the main concepts
like
"resource" and "process", because if a process execution is supposed to end
when the artifact is generated, maybe it would be better to associate the
time to it.
