(a).(Please enter month (write out the word), then date, then time, then am or pm) What date will it be?
(b). The earliest civilizations of which we have records are no more than 10,000 years old. What date and time does this correspond to?
:
 = .0063072 sec = 1 yr
then
.0063072 * 10000 = 63.072 sec is 10,000 years
:
63 sec before midnight Dec 31st:
:
