Zulu Time

[scotty123]

Always thought this referred to GMT - the 0 Time Zone 7.5deg either side of the meridian.

However, on a world map, it shows Z as east of the International Date line.

Which is correct?

I quote Google:

"There are 25 integer World Time Zones from -12 through 0 (GMT) to +12. Each one is 15° of Longitude as measured East and West from the Prime Meridian of the World at Greenwich, England. Some countries have adopted non-standard time zones, usually 30 minutes offset which have a * designation.

Each Time Zone is measured relative to Greenwich, England. There are both civilian designations which are typically three letter abbreviations (e.g. EST) for most time zones. In addition there are military designations. These use each letter of the alphabet (except 'J') and are known by their phonetic equivalent. E.G. Greenwich Mean Time (civilian) or Z = Zulu (military and aviation)."

The Z comes from abbreviation of "zone" in phonetic alphabet. Not to be confused with T time which involves biscuits.

What does P time involve?

Also from Google:

Zulu Time is 7.5 degrees either side of Greenwich. M and Y are 7.5 deg each.

It's a riddle /forums/images/graemlins/grin.gif

There are 24 time zones, and are named alpha for UTC+1 through to zulu for UTC, missing out india and oscar to prevent confusion with 1 and 0

 

[rogerthebodger]

Stingo's location is the only place with true Zulu time.

Also called African Time by us but dont ask why

What, a Jimmy Riddle?

Ahem, I don't wish to start an argument with the esteemed forumite, but biscuits are a feature of morning coffee-time. T time involves CAKES! If you drink enough tea, you become taller lying down than whilst upright!

No, not UTC. Thats a nasty foreign (probably French) invention trying to do away with Greenwich Mean Time or GMT. Maybe the Frogs are fed up of their equivalent, PMT. /forums/images/graemlins/grin.gif

And whilst I'm at it, the name in English is Peking not Beijing, Rhodesia not Zimbabwe etc. Why do we feel the need to alter some English names at the behest of foreign states (and the BBC) bit not others (Munich for example is still Munich not Munchen in English).

Harumph!

You're right about Z being 7.5 deg either side of the Prime meridian; all the rest are 15 deg wide, except M and Y which bracket the date line (mnemonic - MY, MY, MY I'm at the dateline). If you do the math, that's 25 zones - there is no zone J. I remember the convention with the word PONZAB - I know it's not a word but from Z it goes ABC... East and NOP... West.

Sorry to say that you are wrong with regard to "T" time

As far as I'm concerned, "T" time is actually "G&T" time, which of course can be at ANY time /forums/images/graemlins/grin.gif

When I was stationed at GHQ FARELF Signals Centre in Singapore the time zone was GH! How wide was that?

"These use each letter of the alphabet (except 'J') and are known by their phonetic equivalent. E.G. Greenwich Mean Time (civilian) or Z = Zulu (military and aviation)."

I thought so too, hence my question.
However, I am looking at a Collins Wall map of the World, where the zones (time) either side of Greenwich, are shown as Zone M & N.

These Zones start at '0' deg Long & are 15 deg wide either side. So where do they get M & N from?

It looks like Collins got it wrong! /forums/images/graemlins/grin.gif

About as wide as Singapore, I imagine. That would be 7.5 hours ahead of Greenwich, no?
