If the local time was 7:36 PM, the local military time would be 1936, and it would be spoken as "Nineteen thirty is a property of Three Creeks Media. There are not two "seven o'clocks" in military time as there is with civilian standard time. The United States military, including maritime, land, and air forces, use a 24 hour clock to save confusion. Note 2: Although not normally utilized in military communication due to the confusion it can cause, the time zone J (Juliet) has be used to indicate the observer's local time in other forums. Note 1: Although located in the Delta Time Zone, local time in Afghanistan is GMT +4 hours 30 minutes. Nautical-military time zone chart with large city references. For example, if the orders were to launch a mission at 1000 Zulu, and your ship was located near Tokyo, Japan in the "India" time zone - the India time zone is GMT plus nine hours, so you would add nine hours to 1000 Zulu, and know your time to launch would be 1900 local time (India). ![]() Depending on the ship or units location on the planet, it will determine the amount of offset required. Zulu time is the same as "Greenwich Mean Time" or GMT. Standard military orders would be delivered in Zulu time. Nautical time zones are used by the military to ensure a standardization of time for the forces. The difference between adjoining zones is one hour. Each time zone is 15 degrees of longitude in width. In order to avoid continual changing of time as one travels east or west standard time zones are introduced. The master clock, also known as the atomic clock, used for standardizing time across DoD is actually dozens of continuously scanned and averaged atomic frequency standards which provide a consistent result within a picosecond (one trillionth of a second)! Within one trillionth of a second - you can't get much more accurate than that! Nautical Time ZonesĮvery meridian has its own mean solar time. United States Naval Observatory Precise Time Department (PTD) is responsible for maintaining a master clock which provides the DoD reference for Precise Time and Time Interval. The Master Clockįirst thing to do is to make sure time is synchronized across the Department of Defense (DoD). For the precision required in navigation and the syncing of mission resources of today's armed forces, everyone must be on the same page. Whether telling the time via the direct observation of the stars or some other means, precision is paramount to the military. The difference between the mean solar time and true solar time is called the "equation of time." There are four times a year the mean and true solar days are equal, by contrast there are also days which time could vary as much as 16 or more minutes. The primary unit of time is the "mean solar day." A mean solar day is the average of the "true solar day," which varies slightly in length. The original standard by which all clocks are regulated is furnished from observation of the stars and their relationship to the earth. The fundamental means of measuring time is the rotation of the earth. ![]()
