Let TO be the object from which the entryTTL attribute is being read.

The value of TO!entryTTL is the number of seconds in TO!msDS-Entry-Time-To-Die minus the current system time, and is constrained to the range 0..0xFFFFFFFF by returning 0 if the difference is less than 0, and 0xFFFFFFFF if the difference is greater than 0xFFFFFFFF.
