If you select the Seconds display option, a second hand appears on the analog-style clock face and icon, and moves like the second hand on a physical analog clock. The digital-style clock face displays the passing seconds digitally.
Figure 7-8 shows both the 12-hour and the 24-hour clock faces with the Seconds option selected.
Choose the Date option on the Props window if you would like to display the date at the bottom of the Clock window, as shown in Figure 7-9.
