Change the time of starting

 Start time is the time the driver disk was first inserted into the tachograph or the start time of manual entries (on the back of the record sheet). It is marked with a green line running from the disk centre. It can be changed in each of the three tabs containing an image of the scanned disk ("Read preview", "Basic data"). This can be done in the following way:
