This can currently be achieved using pass rule restrictions; specifically "Restrict based on the date/time of the event" or "Restrict based on the current time (when the pass is used to place the order)" here is a direct link to the 'Other restrictions' section of our Create pass rules for ticket orders help article --> https://help.eventive.org/en/articles/897284-create-pass-rules-for-ticket-orders#:~:text=Restrict%20based%20on,events%20or%20screenings. Note that the same restrictions can be used to restrict pass rules for pass orders and pass rules for item orders.
