Schedule with Time Picker
There are three controlling units in both the start and end time selectors. The
first controlling unit is the Date Picker. You can select the year, month and day
with it. Once you select the date in a different year, the data file will switch

picker, you can click the "Add" button or "Erase" button to add or clear the
scheduling information within the time period. Remember that only if you click
on the "Apply" button, the scheduling changes will be written back to the data
