This is documentation for Mathematica 8, which was
based on an earlier version of the Wolfram Language.

 RunScheduledTask[expr] schedules and starts a task that will repeatedly evaluate expr once per second. RunScheduledTask schedules and starts a task that will repeatedly evaluate expr every time seconds. RunScheduledTaskschedules and starts a task that will evaluate expr once after time seconds. RunScheduledTaskschedules and starts a task that will try evaluating expr once every time seconds up to count times. RunScheduledTaskschedules a task that will automatically start at start time.
• The start is taken to be the absolute time when the task is activated.
• The first evaluation of expr will occur time seconds after it is activated.
• If two tasks are scheduled to evaluate at the same time, the one added later will execute first.
• A scheduled task does not require a notebook front end to work.
• By default, if the time necessary to evaluate expr is larger than time, the next pending evaluation is skipped.
The timer fires off at the end of the specified three-second interval:
Perform an action the specified number of times:
Create a task that will be activated 5 seconds from the current time and will print 1 second later:
Specify a date to activate the task:
Front end versus kernel clocks:
Create a task with random wait periods:
Create a task that restarts evaluation as soon as it finishes:
