Metric time

[Mawane]

Australia's This Day Tonight news program revealed that the country would soon be converting to "metric time." Under the new system there would be 100 seconds to the minute, 100 minutes to the hour, and 20-hour days. Furthermore, seconds would become millidays, minutes become centidays, and hours become decidays. The report included an interview with Deputy Premier Des Corcoran who praised the new time system. The Adelaide townhall was even shown sporting a new 10-hour metric clock face. The thumbnail (found at TelevisionAU.com) shows TDT Adelaide reporter Nigel Starck posing with a smaller metric clock. TDT received numerous calls from viewers who fell for the hoax. One frustrated viewer wanted to know how he could convert his newly purchased digital clock to metric time.

Mawane could you be more off date? That is so soooooooooooooooooooooooooooo ooooooooooooooooldddddddddddddddd.

Quite funny, but it doesn't make any sense: It says there will be 100 minutes to the hour, and 20-hour days. But then it goes on to say a minute would become a centiday, which would be 1/100 day. A minute should rather be a centihour. Likewise, a second could in no way be a milliday, which would be 1/1000 day. If you make it a 10-hour day instead of 20-hour, you'd get a minute to be a milliday, and a second to be 10 microdays.

yeye, i know old, but interesting idea

would be possible to put 10^x h per day
some multiples of 10 for minutes and seconds too
ofc its not possible to change the amount of days per year cuz there are 365-6 days to make full rotation around sun
weeks and months would be possible to adjust too i guess
there must be a reason for each of units of time, just need to know why

would be possible to put 10^x h per day

So you can have either 1, 10, 100 or 1000 hours/day?
And well, 10000 could work, if you made the hour shorter. I think a year with our current system is some 9000 hours, ye?

solar system is the only reliable clock... so no it's not possible

A month = 3 weeks
a week = 10 days
a day = 10 hours
an hour = 100 minutes
a minute = 100 seconds

a year = 31,449,600 seconds

1 "10-based day" = 100*100*10 seconds = 100,000 seconds

31,449,600 / 100,000 = 314.49600

if a day was 100,000 seconds long, we'd have 314.49600 days.

a week = 10 days.

314.49600 / 10 = 31.449600

that means we'd have 31.449600 weeks in a year.

A month = 3 weeks

31.449600 / 3 = 10.4832 ~ 10.5 (remember, a year is ~ 365 days, and a month is ~ 30 days in our calendar.)

So a year would be 10.5 months.

Might look a little werid, but hey, february has 28 days, july and august have 31. Oh, except for every 4 years, cause then february has 29 days. what's up with that anyway? The "year" as we know it is far from "perfect". If that year is our standard pretty much anything could work.

Sorry if I made any mistakes. Just woke up.

The 24-hour-clock comes from the rotation of Earth, start messing around with different lengths of a day and you're messing with evolution.

Btw Igge, there's a whole bunch of months having 31-days, don't you know the "räkna on knogar-trick"? ;o

Of course I do. I chose july and august merely because they're next to eachother in our calendar. Otherwise our 'month system' goes longer-shorter-longer-shorter-longer-shorter-longer-as long-shorter-longer etc.

And yes, I used the räkna knogar-trick to make sure that july and august were those two months. 8)

If the year has 365.24... days, then to have a "metric time" then days would obviously be fucked up. For example, let's say 1000 days in a year, then there would be days with full sun, days with full night, etc.

And if we decide to keep the same day length and months and weeks and everything but change the 60-thing for 100 or something, with 10 hours of 100 mins which are 100 secs each, then seconds would be 0,864x their current length. So a second would last 864 current milliseconds. Why would we do that?

By the way, Igge, one year has 31.536.000 seconds I think. Maybe my mental calculation isn't perfect though

I thought it was done in degrees...360 degrees in a day, 360 days in a year. Means 60 minutes would be 30 degrees, so a minute would be like two minutes long. That is, if there are two 360 degree cycles like our AM/PM system...
