GPS tracking can be enabled for Clock-In/Out and Check-In/Outs in the PK4 TimeTracker application for users.
Once the GPS tracking is enabled in the org, the location is tracked as soon as the User clicks the Clock-In/Out or Start Job/Travel button. The location details are saved and are visible when you go to the Clock-In or Check-In details tab in Salesforce.
