Isn't it Time for Metric Time?

    but it raises an interesting question, one that's been on my mind a lot lately.

    When is the US going to officially switch to the SI unit system. I know it's taught in public schools, typically in science classes, but it isn't used in public places. If so many European countries can switch currencies without huge problems (so far), surely we can switch from our archaic units system! I don't understand why so many people are so vehemently against making the switch. Is it that hard to (re)learn?

      The story I've always been told is that when President Carter tried to switch the US to the metric system, the aerospace companies stepped in and told him a couple things:

      1) cost plus on government contracts is going to be a much bigger PLUS

      2) it'll hurt US manufacturing by making it easier for those foreigners to sell their products here (without conversion to US measurements)

      Actually, IIRC (and I was alive then),
      Carter was in the process of converting the country to Metric.
      (I particularly remember gas pumps that displayed both liters and gallons.)
      Then he lost the 1980 election to Reagan.
      Reagan stopped the conversion in its tracks, saying something like:
      "We have become world leaders in Science without the 'benefit' of the Metric system"
      (ignoring the fact that most scientific establishments use the Metric system).

      Some of the effects of this aborted attempt are felt to this day.
      For example, many carbonated beverages are now sold by the liter.

      One of the strange side effects that going metric had in Canada is that most Canadians now think of distances in terms of how long it takes to get there, rather than the actual distance in km. The switch happened around 1977. Almost overnight all distance and speed limit signs went from miles to kilometers. Suddenly the sign that used to say:

      Moose Jaw 200 miles

      now read

      Moose Jaw 320 km

      Instead of trying to convert kilometers back to miles, most people simply divided the distance by the speed limit (which stayed the same after conversion to metric) to get the approximate time to their destination. This became very simple because most highway speed limits are now 100 km/h. So 3.2 hours at 60 MPH is roughly 180+ miles. After a while most people stopped doing the second part of the conversion and simply started thinking of distances in terms of time. I'm sure most people who've visited Canada have had this strange conversation:

      Non-Canadian: Excuse me, how far is it to the nearest gas station?
      Canadian: About ten minutes.

    One of the interesting properites about using the 60, 60, 24 is the number of divisors..

    To wit..

    60 can be evenly divided by 2, 3, and 5 (and multiples of those).

    24 can be evenly divided by 2 and 3 (and multiples of those).

    It is also one of the reasons why 12 inches is still popular ( 12 can be divided by 2, and 3) so that you can have 1/2 and 1/3 (or multiples of those) of a foot without getting into fractional inches.

    However decimal (metric) runs into problems. You only get 2 and 5 as the multiples without getting into "weird" decimals. Exactly how many centimeters is 1/3 of a meter? how many millimeters?

  5. base-10 feasable, but 13 months really needed. by Anonymous+Freak · · Score: 3, Interesting

    Yes, you could divide days into funny measurements, and change weeks; but the most needed change is away from the 28/29/30/31-day months (yes, only one has 28, and only once every 4 years is there 29...) The year could be almost perfectly divided into 13 28-day months. (hence the origin of 'month', look it up.) Then you'd be left over with one 'extra' day. It would be perfect for new years. Heck, I also think that the seasons should be CENTERED on the equinoxes and solstices, shouldn't they? So that the very MIDDLE of Summer is the longest day of the year, instead of the very END? And, the year should begin either on the Winter Solstice, or halfway between then and the spring equinox, shouldn't it?

    But, enough of my rambling. I think a 13 28-day month calendar, with 4 perfect 7-day weeks a month, is better. Yes, then you could change the individual days to have metric times, such as 10 'hours', with 100 'minutes' per hour, and 100 seconds per minute. That comes out to 1.14 new seconds per old second. (so a 'new second' would be only slightly faster/shorter than an old second.)

    While we're at it, we need to re-number the years. One: Most of the world isn't Christian. Two: It has been determined that the current calendar is something like 6 years off. So, based on when Jesus was actually born, it should really be A.D. 2008. (I think. I know the 'real' figure has been determined, I just can't remember what it is.) We should re-number based on something definite, that we know factually exactly when it happened. There was one organization a few years back that was trying to get it re-numbered based on the moon landing (it also recommended a 13-month calendar, with 'new years' falling on what is currently July 20, being newly called 'Armstrong Day', and leap day would be 'Aldrin Day', to keep all 13 months always at 28 days.)

They may have even cycled the light every, what, 45 minutes(?) to simulate orbiting the earth.

    I don't remember anything about specially controlled clocks that run a little slower to add the extra hour a day. If there are 3,600 seconds in an hour and 86,400 seconds in a day, then each move of the second hand on each clock actually needs to take 1 + 3600/86400 or 1.041666 seconds.. barely noticeable.

  7. There should be symbols meaning "day" and "month" by Broccolist · · Score: 3, Interesting
    Personally, I like to use the Japanese system in my own personal notes. In Japanese, you rarely use slashes: the language a very nice system to avoid confusion. They have easy-to-write ideograms meaning "year", "month" and "day". E.g. to write july 4th, 2002, you would write:

    2002 <year> 07 <month> 04 <day>

    (where <year> is the ideogram meaning "year", etc.) They also have characters for the days of the week which can be written much faster than English words. I can't write Japanese in a slashdot post, but check out for example the "old stories" sidebar on the right on slashdot.jp to see what it looks like.

    This is so neat that I wish English would adopt a similar system. If we introduced a few simple symbols that meant "year", "month" and "day" and appended them to the numbers, there would never be a problem. Unfortunately, because our writing system is so glyph-starved, and it never even occurs to anybody that characters outside our 40 or so symbols could exist, this will probably never happen.

    As for the Metric system - for time - if anyone wants to see Decimal Time in use, there needs to be a simple way of marking decimal time as Decimal time (a D up the front, perhaps?) so that people don't get confused. Handy conversion ratios and utilities would also help. Then it can be adopted by a few groups of people, bit by bit, and spread as appropriate to its usefulness ...

    The normal 'second' is pretty well entrenched. Come to that, I've seen 'kiloseconds' in use in some scientific contexts.

    I find it interesting that I thought the most awkward thing with establishing metric time would be finding good names for the units (especially the 'hour' equivalents, 1/10th of a day) - then I read the article, and that's a large part of what it covers :-)

    After the revolution, from 1923 to 1931, the russians used a 5 day week, with 6 weeks in each month, and 12 months in each year. The extra 5 days were specially named holidays related to revolutionary dates. Each worker got 1 day in 30 off, staggered throughout the community so no more than 1/30th of the workers were off each day. (Not everybody in russia used the calendar. The navy stuck to the gregorian calendar because all their navigation books were in that format, tribal regions stayed with their historic versions, others just ignored the decree)

    It was a complete disaster, the idea was to get an extra boost from worker productivity by not allowing weekends or other time off. It had the opposite effect, workers were exhausted after 29 days of continuous work, and productivity fell dramatically.

    In 1931, they switched to a 6 day week, with 5 week months, and one day each week was a rest day for everyone. Productivity jumped 50% or more in the first few months of using the new calendar.

    This should be a lesson to managers who try to pull too much work out of their employees. People need time off on a regular basis to recover from the effects of working 8+ hours per day for 5 or 6 days. After spending too much time working, the body and mind can't maintain the output.
