Adjusting the tiome is just like adjusting the date, owith the only difference that you just enter two values (hours and minutes):

1. Move the Grand Total/ Rate Setting mode selector to the "Rate Set" "position
2. Enter the time in the orde of hour, minutes (use a point to separate the two values) and then presse the [Clock/Calendar] button to complete the entry.
