This seems like a pretty basic ask, but can't find anything about it.
Is there a way to create PVA action/response based on time of day? Looking for condition logic that says if systemTime() between XX:00 and YY:00, then.
If you are calling a flow you can get the current hour using FormatDateTime(utcNow(), 'hh:mm'). You can then use that in a condition or send it back to PVA as a variable.
