British Army ZULU

One of two things: a military time standard, or an embarrassing barmy Army dance even worse than the Village People's 'YMCA' of 1978.

Introduction

  • ZULU is a 24 hour clock all forces can use when planning operations with units outside theatre and between Time zones. ZULU time is Greenwich Mean Time, and UTC, without daylight saving time (GMT+0). Universal Coordinated Time is the world's Time standard, simples, but the world of Science has contrived to make it all unintelligible.
  • ZULU is the unitary Time or military time zone used by navies, civil aviation, military forces, and satellites. Traditionally, ship and aircraft navigators use ZULU Time and the Gregorian calendar time divisions of hours and minutes.
  • Time is linked to the rotation of the earth; the length of one day is the 24 hours it usually takes the Earth to spin 360 degrees on its axis. The planet never rotates at a constant rate and it is not perfectly round.

What it Means to drunken Toms

To the Old and Bold, it was also a dance akin to MC Hammer's bone efforts: the protagonist holds a broken pool cue in one hand, a metal dustbin lid in the other, and shakes, leaps and bangs his 'Zulu Shield' (Bin lid) with his Assegai (pool cue) - usually to TOTP music. Other legendary drunken ZULU performances and lyrics are closely guarded secrets, known only to veteran regular soldiers.

Politically Incorrect?

Amongst all the burgeoning, virtue-signalling dribble there are calls to supplant ZULU with ZEBRA (nothing is safe). It's easy to imagine batshit progressives - or meddling loons in civil and public services - turning purple over ZULU Time's colonial and racial connotations. Utterly crayzay, but that's where we're at. And as ARRSEr dingerr noted: perhaps 'ZEBEDEE' [Magic Roundabout] would be politically correct, if meddlers insist on fcuking with the established NATO phonetic alphabet or the Septics, or international Aviation and Maritime protocols.

Universal Coordinated Time

In short, "ZULU" or 'Z' time (formerly known as "GMT" and now UTC as the world time standard regulating world clocks and time) is also time at the Zero Meridian or Zero degrees latitude ("Prime Meridian"), which is the line marking the Equator and dividing the Earth into two equal hemispheres (or halves, north and south).

GMT

The meridian line in Greenwich represents the Prime Meridian of the world, Longitude Zero (0° 0' 0"). The Prime Meridian is the imaginary north-south line of longitude that passes through Greenwich, England, and is used as the basis for longitudinal measurements on the globe. Put simply, in the context of Universal Time: 0 UTC is also midnight in Greenwich (GMT+0).

Greenwich Mean Time is no longer the international standard; GMT is now only a time zone used by a few countries in Africa, and in Western Europe including the UK during winter, and all year in Iceland (timeanddate.com). In winter, the time in Iceland will be the same as UK ZULU (GMT+0). GMT is still widely used as the standard time against which all the other time zones in the world are referenced.

Other Gen

According to Greenwichmeantime.com other countries which use GMT+0 as their Time Zone (they do not use Summer Time / Daylight Saving Time) are as follows: St Helena | Burkina Faso | Gambia | Ghana | Guinea | Guinea-Bissau | Ivory Coast | Liberia | Mali | Mauritania | Morocco | Sao Tome | Senegal | Togo | Western Sahara.

Zero degrees longitude or 0° or 'Z' is an imaginary line known as the Prime Meridian; a prime meridian is a meridian in a geographical coordinate system (GCS) at which longitude is defined to be 0°. The Prime Meridian runs through Greenwich, England.

A geographic coordinate system defines two-dimensional coordinates based on the Earth's surface. The intersection of the Equator and Prime Meridian (zero degrees latitude and longitude) is in the Gulf of Guinea off the coast of West Africa. Crossing the Equator is also known as "crossing the line". This presents another excuse for a piss-up in fancy dress, or cross-dressing parties for Booties.

Simple Summary

ZULU is a unitary 24hr clock for planning coordinated operations between different Time zones. ZULU Time is Greenwich Mean Time and UTC, without daylight saving time (GMT+0). Therefore military ZULU time has nothing to do with Zulus in Africa. In the NATO phonetic alphabet and civilian radio: the word for 'Z' is "ZULU". In the context of Coordinated Universal Time (UTC), the phonetic letter Z means "zero hours". When the time is 0 UTC: it is therefore midnight in Greenwich on the meridian line of longitude zero.

The Prime Meridian is an imaginary north-south line of longitude that passes through Greenwich, England, used as the basis for global longitudinal measurements. The offset from Greenwich Mean Time is zero, in other words Greenwich Mean Time has no offset from UTC (Coordinated Universal Time).
