Since you mentioned the Overview screen, I assume you are referring to the R77.30 SmartDashboard.
From the Firewall tab...Policy, enter "temp" without the quotes in the search box at the top of the rulebase. This will show you all rules with a time limit (whether currently expired or not). Enter "exp" in that same search field to see only currently expired rules.
Strangely enough after a few minutes of poking around in the R80.10 SmartConsole I cannot figure out how to apply the above filters to find rules with time limits. Best I can come up with is doing a "Where Used" on each individual time-based object to clumsily approximate the same thing. Anyone know a better way?
