3.6 Timer Events
As described in section 3.2, the ILS Server maintains an entryTTL attribute that has a value that is a TTL marker for dynamic objects in seconds. When the timer expires (counts down to zero) on a dynamic object, an ILS Server MAY<29> remove it from the database by the server. Client applications need to perform occasional refreshes of the attribute to ensure that the server maintains the dynamic objects. The value of entryTTL can be reset by searching for the attribute sttl. Note that sttl values are in minutes, entryTTLs are in seconds.
