You can check the example here,
Date stored in collection will be in UTC as shown in “No Formatting”, otherwise it will be converted to user’s timezone.
If I create new project with this action button and select both start date and end date to be today, there will be 2 additional actions after update form action that update start date time and end date time marking them as today, as explained in that post.
We can use this start date time and end date time to check any date time outside this range.
You can clone and change as you like.
