Time differences in the U.S.

For the time display in America often a 12-hour clock and not the 24-hour time is used.

00:00 - 11.59 hour is AM (ante meridiem)
12.00 - 23.59 hour is PM (post meridiem)
9.00 uur [nine hours] = 9.00 a.m. [nine a.m.]
14.00 uur [fourteen hours] = 2.00 p.m. [two p.m.]
When the 24 hour system is used, it looks like this:
9.00 uur [nine hours] = 9.00 hrs [nine hundred hours]
14.00 uur [fourteen hours] = 14.00 hrs. [fourteen hundred hours]
