I was going to make a hash with keys of ProductName and user@host, and store a string consisting of the date and time for each OUT record

I thought about just concatenating time+date+product+user@host into one string and pushing it on an array, and then scanning that array

If you pushed that string from your first suggestion onto an anonymous array, it would be much easier to process. You basically end up with a hash of anonymous arrays that are more easily searched.
