UTC is Universal or Greenwich Mean Time (GMT)
as measured from the Prime Meridian at Greenwich, United Kingdom.
The official military, aviation and navigational designation for Greenwich is ZULU.
| Military or Universal time is easy to understand after a little practice. There is no AM or PM, the day is divided into 24 hour segments. The simplest and quickest way to calculate military time when you are just learning it is to understand that all numbers higher than 1200 constitute PM. The next time you are watching a movie and a soldier says its "2235 hours" use simple subtraction to find civilian time: 2235 - 1200 = 10:35 PM. |
