# Timers

A Timer is an object that periodically executes a Global Action Set or Local Action Set. You can have up to 10 simultaneous Timers per Form. These Timers can be executed in a threaded mode. See “[Start Timer](/kalipso5/developing/form/actions/actions-description/group-date-time/start-timer.md)” and "[Stop Timer](/kalipso5/developing/form/actions/actions-description/group-date-time/stop-timer.md)" Actions for more information about using a Timer.

For your own organization, you can name the Timers. Select the Timers that you want to rename on the Table and press the button to edit its properties.

* **Timer** - Timer Identifier. You cannot change this value.
* **Name** - Timer Name. Name that you want to give to the Timer. The name of the Form should only contain letters, digits or underscore (\_). This is the Name that will identify the Timer throughout the Project.
* **Description** - Timer Description. The description that you want to give to the Timer. This property is for your information only.
