Correct way to write 24 hour-time? Decimalpoint too.

In France railway timetables etc put an 'h' after the hours figure so 11 minutes past six in the evening is written 18h11 and pronounced "dix-huit heures onze"

Where did your 16 come from??
Broaden your mind.
In Engalnd we use a dot as the conventional decimal 'point' or poinr where the integer numbers end. On the Continent they conventionally (in some countries) use a comma.
Another fact is we tend to use the 'x' as the abscissa in England, and the 'y' for the ordinate. This is reversed in some countries on the continent.
The fundamental thing to do is to learn to understand what concept you are looking at or reading of, then the convention does not matter provided you can follow through the logic in terms of the convention the authore has used.
In maths we have a two fold use of the point.
It can be on the line or half way up and either way it indicates the integer stop point.
A dot can also indicate the arithmetical function ususally written as a 'x', multiplictaion.
The sexagesimal system of recording time, with 3'30''32
followed by a 'o' superscript, would read as 3hrs and 30 minutes 32 seconds AM. The same thing is indicated by 3:30:32, or by 03:30:32.
To translate it to decimal you divide the minutes by sixty, and the seconds by 3600 and add the results to the hours.
e.g. 3:30:32 = 3+(30/60)+(32/3600) = 3.509
In the 12 hour format the AM or PM should be used to indicate ante or post meridian. In the 24 hour format this is not necessary as the tme progress to the 13th hour etc. when the 1st hour post meridian is hit. In this case midnight is wrotten as 00:00:00.

Here in Europe we use 24 hour time a great deal.
Laymen and even old ladies both use it.
If you make a contention that applies only to the US then that's ok but that is not where I live.

Hi Alex_Coleman, For myself, I write 18 hours 16 minutes after midnight as 6.16 P. If it was something that happened 18 hours 16 minutes ago, I write it as .761 days... ( 18 + 16 / 60 ) / 24 .

Wel, i did some introspection, as European, if in the Netherlands at say 16:48h somebody askes you 'what time is it' (in Dutch: Weet U ook hoe laat het is?), I would reply with '12 voor 5' (12 to five). Because of the context people usually KNOW if it is morning or evening.

Maybe - but you wouldn't do that on the phone with someone calling from "het buitenland" :-)

But, as you are insane, you don't count. I am sure _you_ find it easier to write .761 days than 18 hours, 16 mins but I doubt even you would find it easier to think and communicate to others in that manner. ("I will meet you in .761 days" is just insane)

Yes that is the problem, I have a little program 'kworldwatch' (Linux) that displays a worldmap and shows where it is still light. A watch with a function like that (when all is UTC) would make sense.
OTOH when you call your boss from the 'other side', you get a tape that says: 'office hours from ww:xxh to yy:zzh', or he will use some sleepy bad language, or he will be happy with the new contract.
But in case of 'events' (phone conferences for example, meetings, etc..) it would make a lot of sense. And that annoying updating the watch on the plane stuff would be gone.
Jetlag would stay though.

Good for you. Its still crappy and slightly insane.Stop cross posting to groups that really aren't interested in you (which would mean pretty much all of USENET but you _still_ refuse to get a blog)
Are you rich yet?
Did you resolve your confusion over the spatial dimensions and my being an accountant?

So someone in Sydney might have office hours of 00:00h to 08:00h UTC and in London 08:00h to 16:00h UTC and NY office hours would be 13:00h to 21:00h UTC. How is that less confusing??
Okay, then when you land, the first thing you ask at the airport is, "What time to people here eat their noon meal, and when is 'normal' working hours?". The answer might be, "We tend to eat lunch about 20:00 and the bank is open from 17:00 to 01:00."
Yeah, that's a *lot* more convenient than resetting your watch..... *NOT*

Your solution doesn't solve any of those problems though. When communicating between time zones, the sun is a poor indicator of who is working when etc.

Now it does. I haven't a clue what that double dutch means, but I think there was a server problem with the site when I tried to access it. ;-) This one is a little nicer:
