Switching to decimal time;

As we have decimalise many things over time, like money, weights, measurements etc.
Isn't it time that we decimalise time?

The old 24 hour clock system.
24hours = 1 day
12hours = ½ day
60minutes = 1 hour
60seconds = 1 minute
86,400seconds = 1 day
The new 10 hour clock system.
10hours = 1 day
5hours = ½ day
100minutes = 1 hour
100seconds = 1 minute
100,000seconds = 1 day

The old 24 hour system.
The local time in your area is (12 hour, ½ day clock)
The local time in your area is (24 hour, 1 day clock)

The new 10 hour system.
The local time in your area is (5 hour, ½ day clock)
The local time in your area is (10 hour, 1 day clock)
The old 24 hour and new 10 hour analogue clock faces.

Old 12 hour (half day) clock face. New 5 hour (half day) clock face.

If you wish to convert a 12 hour analogue clock into a 5 hour analogue clock then;

1) Print-out the 5 hour clock face below,
2) Cut-out the picture, (don't forget the hole in the centre)
3) Remove the hands from your 12 hour clock face,
4) Stick the new 5 hour clock face onto your clock,
5) Put the hour hand back on.

If your clock strikes-out the chimes on the hour then you must turn-off or disable this feature.
Also as the minute hand moves round the clock face twelve times in half a day (old 12 hour clocks)
and not five times (new 10 hour system) you should only replace the hour hand.

The problem with time zones.

The new time zones.
As a day is now divided into 10 hours and not 24 hours there are just ten time zones around the globe.
The time zones will still be an offset from GMT (Greenwich Mean Time) or UTC. (Coordinated Universal Time)
This means that 12:00:00 gmt (24 hour clock) = 5:00:00 gmt (10 hour clock)
but 12:00:00 gmt+1:00 (24 hour clock) is not 5:00:00 gmt+1:00 (10 hour clock)

So as countries switch to the ten hour system, if their time zone is not GMT+0:00, then they will need to use the following format;
  • Your local time - GMT offset (Convert from local time to GMT)

  • 24 hour seconds x (100,000 ÷ 86,400) (Convert from 24 hour format to 10 hour formar)

  • New 10 hour system GMT time + Your new time zone offset (Convert from GMT to your new time zone)
    Your current local time (24 hour time) =  :   : 
    Your current time zone (24 hour time) =
    Your new time zone (10 hour time) =
    The new 10 hour time (GMT) =
    - Unknown -
    The new 10 hour time (Local time) =
    - Unknown -
As the time zones are bigger, more countries will share the same time zone, but the time difference between time zones will end up being bigger.
So more countries may end up using half hour time zones. (Eg. Local time = GMT+01:50 for Moscow)
1 new hour (10 hour format) = 1/10 of a day.
1 old hour (24 hour format) = 1/24 of a day.
So 1 new hour = 2 hours and 24 old minutes.
Half a new hour = 1 hour and 12 old minutes.

The average working day is 9:00am to 5:30pm (24 hour format)
This will change to 3:75am to 2:29'16pm (10 hour format)
2:29'16pm may be rounded down to 2:29'00pm, giving us a shorter working day by 16 seconds (or 14 old seconds)
If your boss does not like you, he may round it up to 7:30'00pm.
The one hour lunch break may become a thing of the past, as most managers may say that this is 25 minutes too long.

Once this system has been introduced into all countries, the next step will be to decimalise the whole year into 100 days.
This will take some doing as the speed of the Earth travelling around the Sun will have to be increases by fitting large rockets to the Earth.
If we also decimalise months, then the speed of the Moon will also need adjusting.
