Timer
Timer is a process starter activity that starts the process at a specific time. You can also specify the processes to be started periodically.
General
The General tab has the following fields.
Field | Literal Value/Module Property/Process Property | Description |
---|---|---|
Name | None | The name to be displayed as the label for the activity in the process. |
Start Time | Yes |
The day and time to start the process. To run the process periodically, the start time indicates the first time to run the process. The local machine’s time zone is used to determine the process start. If the project is running on machines in different time zones, the time zone of the machine where the project was saved, is used. Use a process property in this field to provide start times relative to the time zone where the project is deployed. If you provide a process property for this field, the format of the specified time must be: yyyy MMM dd HH:mm:ss z |
Run Once | None | Indicates this process should be run only once on the day and time indicated by the
Start Time field.
If you do not select this check box, the Time Interval and Interval Unit fields are displayed that you can use to specify the frequency of the process. |
Use local time | None | On selecting this check box, the local time of the container is considered. |
Time Interval | Yes | The integer indicating the number of units specified in the
Interval Unit field. For example, if a value of
1 is specified and the

Description
Provide a short description of the Timer activity.
Advanced
The Advanced tab has the following fields.
Field | Description |

Sequencing Key | This field contains an XPath expression that specifies which processes should run in sequence. Process instances with sequencing keys evaluating to the same value, are executed sequentially in the sequence the process instance was created. |
Custom Job Id | This field contains an XPath expression that specifies a custom job ID for every job in the process instance. |
Output
The following is the output of the activity.
Output Item | Description |
---|---|
TimerOutputSchema | The time the process instance started.
The time is represented by several items in the output schema indicating:
Each of these items uses the appropriate datatype. |
