Converting 24-hour time to 12-hour time is what this item tests. In 24-hour format, hours range from 00 to 23, with AM from 0000 to 1159 and PM from 1200 to 2359. The time 0300 has an hour of 03 and zero minutes, placing it three hours after midnight. That is 3:00 AM. For contrast, 1500 is 3:00 PM, and 1200 is noon, while 0000 corresponds to 12:00 AM. The leading zero is just formatting; 3:00 AM can also be written without it.
