Reading the documentation you posted again after posting this question, it does sound like it's simply a placeholder that only gets filled in when used by an operator, then again, that's still not exactly what it says so I only feel 70% confident like that's what is happening.

Hello,

When using PROCTIME() in CREATE DDL for a source, is the proctime attribute a timestamp generated at the time of row ingestion at the source and then forwarded through the graph execution, or is proctime attribute a placeholder that says "fill me in with a timestamp" once it's being used directly by some operator, by some machine?

Thanks!
