It also addresses the problematic to +of non-metric conversion when used with other +units. + +**Simple Universal Time (SUT)** +is suited for instant implementation and does +not interfer with any current time system. + +## Motivation + +The life of individuals becomes more and more +global: + + * Communication takes place covering several time zones + * Travelling accross multiple time zones has become normal + +Due to this change, people are more and more confronted to +think about the time in different time zones. + +To place a call, you have to find out + + * in which time zone the target person is + * how much offset to UTC this particular time zone has + * remember the delta from my time zone to UTC + * create the delta from both time zones + * find a good time for a call + +This is quite cumbersome and wastes a lot of energy +world wide, every day. + +Furthermore, changes from summer time to winter time zone +make this process even harder: If you remember the offset +for a particular location, the time zone may have changed +due to summer time changes... + +There is another problem with the current time scheme: +that is being non-metric. Having scientific +calculations with all metric units is usually broken up +due to the non-metric behaviour of time. This is simply +unecessary and can be easily fixed as the following +proposal will show. + +## Proposal + +To simplify this time disaster, the following two changes +are proposed for change: + + * Convert the time of day to a metric system + * Drop all time zones and only use SUT + +### Conversion to metric + +For a simple start, assume there is no time definition and +that we can start from scratch. Assume: + + * A day has 10 hours + * An hour has 100 minutes + * A minutes has 100 seconds + +This would create a day that has +**10 * 100 * 100 = 100000*** seconds. + +The old scheme used to have 24 hours, 60 minutes per hour +and 60 seconds per minute, which resulted in +**24 * 60 * 60 = 86400** seconds. + +Let us prefix the new definition with the word +**simple** to be able to distinguish between the two schemes and +let us convert them into another: + + 100000 simple seconds = 86400 seconds # divide by 100000 + 1 simple second = 0.864 seconds + +Or the other way around: + + 86400 seconds = 100000 simple seconds # divide by 86400 + 1 second = 1.157407 (periodical, rounded) + +### Drop all time zones + +To be able to have one global time that everybody can use +without the need of calculations, there won't be any time +zones defined for use with **SUT**. Instead, SUT is based +on UTC. + +### Time format + +As SUT only includes 10 hours, you can display time of the +day using the following format: + + H:MM:SS + +where **H** is in the range of **0-9**, **MM** in the range of +**00-99** and **SS** in the range of **00-99**. + +## Implications for Society + +When changing to SUT, societies productivity will +improve pretty fast. +If a particular society wants to keep the +unclear advantage of summe time, it can even do so by using +SUT: + +Instead of changing the time, this society can announce that +all shops open up earlier in summer and open up later in +winter time. Beware: An actual advantage of using summer time +for a society using **summer time** of one that doesn't +**has not been proven**. + +## Using SUT + +You can start right away to use SUT in your daily work. + +SKMP created a javascript implementation of SUT, so you +can easily see the current time: + +[[js.html]] + +The source is available +[at github](https://github.com/telmich/sut). diff --git a/docs/sut/js.html b/docs/sut/js.html new file mode 100644 index 00000000..9daeafb9 --- /dev/null +++ b/docs/sut/js.html @@ -0,0 +1 @@ +test
