Zulu (Zulu time)

Zulu (short for "Zulu time") is used in the military and in navigation generally as a term for Universal Coordinated Time (UCT), sometimes called Universal Time Coordinated ( UTC ) or Coordinated Universal Time (but abbreviated UTC), and formerly called Greenwich Mean Time. In military shorthand, the letter Z follows a time expressed in Greenwich Time. Greenwich Time, now called Universal Coordinated Time, is the time at longitude 0 degrees 0 minutes - the prime meridian or longitudinal line that separates East from West in the world geographical coordinate system. This line of longitude is based on the location of the British Naval Observatory in Greenwich, England, near London. "Zulu" is the radio transmission articulation for the letter Z.

Traditionally, ship and airplane navigation is conducted using Zulu time. Zulu time is usually expressed in terms of a 24-hour clock using the Gregorian calendar time divisions of hours and minutes.

What is the relationship between ZULU time and the military phonetic alphabet found here: http://www.militarytime.us/military-alphabet/

Was Zulu time created by the military?

The concept of Zulu time was NOT created by the military - per se'. The British originated it and called their little island the center of the universe for Earth's Time Zones; therefore they are ZULU and everyone else adjusts to that time beat from Greenwich England. Navigation at sea requires this as another tool when using the sextant and navigating by the sun and stars. A lost art. I last taught the 3rd mate of tug boat how to do it in 1977 - I quit sailing because as an Able Bodied Seaman I knew more than all the mates that I ever sailed with and lost confidence in their abilities. Being a Ship's Boatswain for decades, one tends to pick up a lot of useful information - if you are the type to absorb information like a sponge. Semper Fi!

BTW - I had been ship's captain in another life. Being an actual "Sea Captain" doesn't always denote one's present rank, more their qualifications to take a ship someplace and bring it back. In my case I learned in Vietnam where we had another little twist tossed in - besides the shooting, mines etc. there were NO navigational aids - NONE! So much fun... Semper Fi! (Yeah - that's because I was a Marine first - OK?)

Comes into context with aviation, imagine fast jet serviced at 08:00 local in one time zone then travels west and crashes elsewhere at 07:00, good one for lawyers.
