System Date

System date corresponds to the actual calendar date. At any hour on the 9th of September in the year 2000, the system date is the 090900. At the end of the day, when midnight is reached, the system date changes to the 10th of September (100900).

(Of course, your system clock can be set incorrectly. For example, if the system clock is an hour slow, then your system date will not advance at midnight, but rather at 1:00 a.m. Assume that your system clock is set correctly, and that the system time and date correspond to the true time and date.)
