3.) 24-hour Clock
It’s not 1400 hours … it’s 2 o’clock. Since most companies operate in the 9-to-5 time frame, the need to distinguish between the first 12 hours of a day and the second is not so great. If you are working at an office and a project is at 3 or a meeting is at 11, it is pretty easy to determine what time is actually meant. If, for some reason, you are working somewhere with extended hours, like retail, then just add a simple a.m. or p.m. as necessary.
