How can I pull submission date/time data from a SquareSpace form to use for path trigger without making the user input it?

Hi I am a mental health therapist and I am trying to build a zap to connect the the clients with our therapists automatically when there is a square space form submission.  To make it more look like a human, I need to extract the time when the form is submitted to make sure the zapped email are not sent in the midnight hours, say if a client sends a form in 11:00 p.m. How can I find a way to extract the form sending time and use it in paths to help zap sending emails at reasonable hours. 

Thank you!
