Workflow immediate action


I am testing a workflow to update Contacts status field value 3 min after a contact record was updated. After the update the status was modified right away, it does not wait for 3 minutes. What could be the issue here?

Workflow settings:

Run: Always
Run On: Modified Records
Module: Contacts
Field: Date Modified
Operator: Less Than or Equal To
Type: Date
Value: Now - 3 Minutes
