# Time **Time-based actions** occur at designated times, such as daily at 6 a.m. When the specified time arrives, the workflow rule reassesses the record to ensure it still satisfies the rule criteria. If so, it executes the specified actions. The **Time** trigger requires a cron expression. The workflow instance starts when the time specified in the cron expression matches the current time. The execution of this trigger does not add execution variables. For the **Time** trigger, Data Mover provides a set of **system workflow templates** that must be used in input contracts. You can find the complete list on the [Workflow templates for input contracts → Trigger type: Time](/data-mover-1.21/workflow-templates/system-workflow-templates/workflow-templates-for-input-contracts.md#trigger-type-time) page. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.primeur.com/data-mover-1.21/workflow-templates/triggers/time.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
