Java in a Nutshell, 5th Edition [Electronic resources]

An object that implements this interface has an associated delay. Typically, it is some kind of task, such as a Callable, that has been scheduled to execute at some future time. getdelay( ) returns the remaining time, measured in the specified TimeUnit. If no time remains, geTDelay( ) should return zero or a negative value. See ScheduledFuture and DelayQueue.
