What to know before using the result.
Is 0000 midnight or noon?
0000 is midnight at the start of a day; 1200 is noon.
Does military time include a time zone?
Not by itself. A 24-hour clock value needs a stated zone when people in different locations must refer to the same instant.
How are afternoon times converted?
For 1:00 PM through 11:59 PM, add 12 to the hour; 12 PM remains 12.
