The Future of Time: UTC and the Leap Second



Please, permit me a proposal on subject matter.
My name: George Theodosiou
My social situation: Homeless, jobless, penniless, secondary school graduate.
My interest on the matter is due to I like observe solar time as Humanity does from its creation.
My proposal:

1. Rename UTC to UCT (Universal Civil Time). Some muliple of second SI to be its unit.
2. Establish infinite set of multiples of secSI as follows:
3. Initial multiple of secSI' factor to be (9,192,631,770 + a) /9,192,631,770. Number (a), integer, to be determined by Earth Orientation Center in order to compy with present 1/86400 of mean solar day, and announced at least one year before be in effect.
4. Each year, some amount (an), integer too, to be added/subtracted to/from numerator in order to comply with earth slowing
and condition |UCT - UT1| < 1 sec. This amount also to be determined by EOC and announced some months before Jan 1st to be in effect from this date.

Remarks: Number (a), my estimation is about 154, will need special care by Network Time Protocols.
Also number (an), I estimate 1 or 2 (maybe sometimes negative) , will need some provision in NTPs.
Anyway modification in software is the must, and it cost, but you can't solve any problem without some cost.
Comment: I have sent similar proposal to BIPM but I think if ITU, with some 180 member states,
accept it, then BIPM with only 55, will accept it, too.
If BIMS objection is that mutiple factors aren't integer numbers, answer is: from second SI
definition follows, it's a multiple of the period etc of cesium atom etc, which (period) really is the unit of time. In other words unit of time is 1/9,192,631,770 of second SI, therefore factors I propose, are integer multiples of really basic unit of time.
I'm sorry for my bad english.

With regards
George Theodosiou
