Priorities of overlapping times

Example: An employee’s normal work time starts at 8:00AM, Travel time starts at 10:00AM and Stops at 11:00 AM, and finally the normal time stops at 12:00PM. There are multiple times punched and it overlaps as well. The priorities can be set for this overlapping time by specifying the exact number of hours into each time category. While generating actual attendance, the highest number takes priority over the lowest number that is registered.
