Following your sequence of events, it sounds like you need to know the previous state value.  You can easily do this with a before Update Business Rule (previous.state).  Since you want the date field to populate when the form is submitted the updated from the Business Rule will display whether it is a Save that stays on the current form, or Submit redirected elsewhere.  If this must be a client script for some reason, you'll need a Display Business Rule to capture the state value in a scratchpad variable when the form loads, then you can access the value of the same scratchpad variable onSubmit.
