Time interval objects allow you to create a rule that only matches during certain periods of time, such as on weekend days, during work hours, or other periods. Time intervals operate based on the time as known by the firewall device.
Time intervals can be certain days of the week (only on Mondays, for example), only certain times, and/or only during a certain range of dates. You can combine these options to create an object that represents, for example, Tuesday afternoons from 1 to 3 PM during March of 2011.

In Figure 5.129, the object would be valid from the beginning of Dec. 19, 2009 and end the beginning of Jan. 4, 2010. This might correspond, for example, to a "winter break" at some institution when access to some networks could be restricted.
Another possibility is to limit recreational activities to non-work hours.
In this rule, the "quake" protocol is allowed from the internal network after hours and during weekends. Otherwise, the final "deny all" rule in the rule set would prevent it during other times (during work hours).
