Timer Control

A timer monitors elapsed time:

When a specific relative amount of time has passed (e.g., an hour)
When a specific absolute moment has passed (e.g., midnight of February 12, 2015)
At recurring intervals (e.g., every ten seconds)
After an absolute time or a relative amount of time has passed, in recurring intervals thereafter (e.g., after an hour, then every five minutes thereafter OR after noon on Tuesday, then every hour thereafter)

The BEA Workshop for WebLogic Platform (Workshop for WebLogic) timer control allows you to easily incorporate timer functionality into a web service.
