Run a script Action: How to create a time-based filter on a view

Hi team! I’m looking to schedule automated tweets and found this:

Can I set up a script to run on a schedule using Automations?
At the moment, there isn’t a built-in way to set up a script that runs on a regular time-based schedule (e.g. every day at 9am). A workaround is to use a time-based filter on a view.

I’m wondering if anyone could please explain what a time-based filter means and how to use it?
