The Colonies are getting uppity again :-)

Two observations:

"The Colonies" or "the colonies"?

How much hubris is in your statement? Isn't that hubris the very reason for the state of the world today?

I have wondered for a long time why the rest of the world so easily accepted England's definition of longitude with the zero point set by them. I assume it was because, at the time it was established, Britannica ruled the waves.

One time standard is fine with me, but until that happens, I just wish I could change my Message board preferences to show what I currently observe as my time, which is EST.

The mind is a weird and mysterious place

Seti has standardised on UTC Gordon, as most scientific stuff has. It's the content of messages that matter not the time they were sent.

Oh well, phooey. I'll go back in my little hole. ;~)

BBC

it's not a problem with GMT & UMT...unless a politics come into view! ;)

more problem is "Daylight saving", especially in our society...in which daylight savings doesn't produce no savings @ all...

so if u agree, sign here:

DST has nothing to do with GMT or UTC. We do not sign petitions in a science thread. Go bang your personal drum elsewhere please.

Chris i'm not shore your correct about Australia . I have not herd anthing about changing from UT . One state has Western Australia but i don't think it's got anything to do with opting out of UT . It's more to do with daylight savings .

Just because some are calling for us to become a Republic doesn't mean we are going to opt out of world standards unless said standards are crap anyway .

You cheeky blighter you :)

When did you get to decide the rest of us do not sign petitions in an s@h science thread?

I found other sources that indicate the UK did not invent longitude.

You are about right Bob. The UK did start it, and other nations were happy to join in.

Greenwich Mean Time (GMT) is the mean solar time at the Royal Observatory in Greenwich, London, from 1675. GMT was formerly used as the international civil time standard, now superseded in that function by Coordinated Universal Time (UTC).

As the United Kingdom grew into an advanced maritime nation, British mariners kept at least one chronometer on GMT to calculate their longitude from the Greenwich meridian (for navigation), which was by convention considered to have longitude zero degrees, internationally adopted in the International Meridian Conference of 1884. Greenwich Mean Time was adopted across the island of Great Britain by the Railway Clearing House in 1847, and by almost all railway companies by the following year, from which the term "railway time" is derived.

The main point is that the world now uses UTC for all precise scientific measurements, but by convention we use GMT in our daily lives. People still set their watches by the pips on the 6 o'clock news, despite modern radio controlled clocks. Old habits die hard.

UTC was officially formalized in 1960 by the International Radio Consultative Committee in Recommendation 374, having been initiated by several national time laboratories. The system was adjusted several times until leap seconds were adopted in 1972 to simplify future adjustments. A number of proposals have been made to replace UTC with a new system that would eliminate leap seconds but no consensus has yet been reached.

The current version of UTC is defined by International Telecommunications Union Recommendation (ITU-R TF.460-6), Standard-frequency and time-signal emissions, and is based on International Atomic Time (TAI).

Daylight Savings Time is decided upon by individual countries as well as it's duration and is not used by the scientific community as such. My original post in this thread was more about how and why the zero meridian was selected to run through Greenwich, England and not, say, Madrid, Spain or Lisbon, Portugal both early seapowers.

Yes. It's strange when you think about Colombus and Vasco da Gama who didn't used GMT or UTC.
In navigation it's difficult to know what longitude you are in.
So you used a clock and dead reckoning.

There was a documentary program on the Science Channel about his effort to build a reliable chronometer that would work at sea. Delicate equipment on ships at sea in those days had a rough go of it and keeping the time piece relatively level was nearly impossible. Nowadays anybody with a cheap digital watch and a way to figure out when local noon is can figure out their longitude with enough accuracy to navigate to their destination.

Anybody else wondering?

Well start one then!

What do you mean?
A special thread for petitions?

Janne, he is simply avoiding the question.
KLIK already provided the two above.

well, it's easy...it was agreed upon 2:

don't know why d fuss again?

Science Channel is producer of docus like "Through the Wormhole".
History Channel however are producers of "Ancient Aliens", "Hangar 1", etc.
No science, all crap... Perhaps amusing:)
