I was reading this: [url]http://www.facepunch.com/threads/1080810-Why-can-t-everyone-just-stick-to-the-same-unit-of-measurement[/url]
Really, how hard would it be to make time metic, I can understand it would be a worldwide thing and alot of things would have to change, but the actual process wouldn't be that hard to do. Can some explain to me how this would work?
I'm like 99% sure that almost everyone uses the same units to measure time.
Why?
the second is the SI unit of time so its already metric, there is no imperial measure of time
The second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom.
At sea level at 0K.
Ys but i mean like a 10 "hour" day and a 100 "day" year ect

Days don't work that way.
It takes 365 rotations of the earth for earth tot completely revolve around the sun once. I don't see why the length of a year should be changed.
I guess I could live with a metric thing of 10 seconds = 1 minute, 10 minutes = 1 hour and 10 hours = 1 day, but what's the point of changing it like that? It'd just stretch the seconds to become longer and be a pain in the ass.

Well months are related to the moon, so you couldn't artificially lengthen them so that there are 10. And a year is the earth's orbit of the sun, which you obviously can't synthesise either. Hours in a day could be changed (hypothetically) because they're not based on natural phenomena, but seconds are so it would be a pointless exchange.
Well we could all start using kilo-seconds and mega-seconds instead of hours and days but it would get quite confusing.

yes

Only because "the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom" (wiki), so shorten the number of "periods of radiation".
The second was once not based on anything.

Because everyone in the world uses the current format, why change it now?
The difference with metric and imperial for measurements though, most of the world uses metric and so it IS a problem
Yeah. Our system of time (outside of hours and sub-measurements) is based on the sun, making it the only logical measurement of time.
Measurements of size, weight, and distance are based on [i]nothing[/i], making any system of such measurement feasible. Metric is arguably better, though.
Time is one of the few things that all humans agree on, please don't try to change that.
Wasn't the length of a second decided many years ago by how long it took the moon to pass between two stars.
If we redefined the second we'd have to redefine the meter as well. No thanks.
We could all write day-month-year tho.
Why the fuck would you write it as month-day-year?
Because we say, "March 2nd" and not "the 2nd of March."

Let people decide on how they should read the time.

But if I'm including the year I'll say it 2nd March 2011.

Actually both the meter and kilo is based on something.
Meter then: Originally intended to be one ten-millionth of the distance from the Earth's equator to the North Pole (at sea level).
Meter now: Defined as the length of the path travelled by light in vacuum in 1⁄299,792,458 of a second
Kilo then (Well, gram, but still): The gram was decreed in France to be equal to “the absolute weight of a volume of water equal to the cube of the hundredth part of the meter, at the temperature of melting ice.”
Kilo now: [img]http://upload.wikimedia.org/wikipedia/en/thumb/d/d1/Denmark%E2%80%99s_K48_Kilogram.jpg/234px-Denmark%E2%80%99s_K48_Kilogram.jpg[/img].
That cylinder weighs 1kg + 81 µg.
Light travels 3.0*10^8 meters per second.
Change a seconds length and about 90% of physics has to be re-thought out to fit the new scale.

I'm trying to remember where it's common to write dates YY/MM/DD.
It's a pretty useful format, because a list of dates sorted alphabetically and chronologically are the same, so it's good for timestamps in filenames.
But it's really awkward to say, "2011, April the 22nd".
Fuck mm/dd/year
if you do that then you might as well have the digital clock displaying minutes/seconds/hours.
We use the Gregorian Calendar, it's the most accurate one ever made.
No changes necessary for a long time.
