When an employee is working without access to the internet, offline time tracking software is used to keep track of their time at work, productive time, and idle time. This is the sophisticated method for synchronizing the offline data when the internet connection is restored. For example, suppose an employee works on a Google Chrome page and loses internet connection in the middle. In that case, Desklog will measure the employee's productive time even if they are not connected to the internet. If an employee is paid by the hour, they can charge their billable hours using a time tracker that tracks online and offline working time.
