Hours in the time book can be freely moved to another time and other employees by dragging and dropping.

If the time is not visible in the same one, you can click on the hour from the time book and select Move

You now see a week view for the employee and can easily click in the calendar to select a new time. From here you can also switch between the different employees' time books to move across employees.

When an hour is moved, it becomes visible in the time log and is marked with the name of the person who moved the appointment.

Additional information:
You must delete and create a new hour to move an hour to another department.
