What is task release time in the context of an OS scheduler

Question

In the context of a scheduler, what it means by the release time of a task? Is it the time taken to execute the task?

Answer 1

release time is the earliest time when a job/task can start execution. the other term is deadline which is the time by which processing must be completed. the focus on "can" and "must" will realize you the actual meaning of these terms in scheduling.
