Timed Evaluations
Mathematica's scheduled tasks provide a way to set evaluation of arbitrary expressions in the future. Tasks can be scheduled for one-time evaluation, or for repeated evaluation at regular intervals. Scheduled tasks work independently of the notebook front end.
RunScheduledTask schedule and run a task to perform timed evaluations
CreateScheduledTask create a task to perform timed evaluations
StartScheduledTask start a previously created task
StopScheduledTask stop a running task
RemoveScheduledTask remove a previously created task
ResetScheduledTask reset task parameters to the original or given setting
ScheduledTasks give a list of created tasks
