[[!meta title="Simple Universal Time (SUT)"]]
## Introduction
This article describes a simple solution to the
problem of having to care about time zones,
clock adjusting due to summer and winter time
changes. 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:
