It is obvious that the current time system with the 60/60/24/7/28,30,31/12/365 steps is way too complex.

However, one second is a SI unit, so it would mean too much work to redefine it cleanly. Besides, I do not want to interfere too much with one fundamental unit of Unix.

I therefore define the following units in time_10 to resemble the currently used ones:

A current day has 24*60*60 seconds, this maps to 1.1574 d_10. Our day is thus 15% longer, meaning more time for work, hobbies and sleep!

Therefore, a current week has approximately 6.05 d_10; implying that one's schedule will be sync'ed with the normal day once about every week, which is good enough for shopping.

My job contract states I have to work 40 hours per week; this means I work about 24% total time; given that I work in IT, lets say I work 25% of my time, which is easier to calculate.

In my new scheme, this maps to 25 h_10 per wk_10; implying 5 h_10 work on 5 d_10 out of a 10 d_10 wk_10 - so I have 50% of all days off, not even taking vacation time into account, without actually working less; in fact favoring the employer because I am working 25% instead of 23.81% of my time.

The solar year

The solar year is an important unit, because I want to stay roughly in sync with the seasons.

The tropical year 2000 anno domini had 365 days, 5 hours, 48 minutes and 45 seconds; or 31556925 seconds. Or, pi * 1.0045 * 10^7 seconds; within 4.5 per mille, this is pi 10^7 seconds; this is well within metering precision, and I presume this slight imprecision is either due to the moon being blown out of the earth or the ellipsis not being perfectly accounted for.

Therefore, a tropical year has PI * 10 wk_10.

We haven't defined an equivalent for a month yet, and I would like to do away with it. One approach might be to define:

However, it is trivially obvious that this doesn't result in nice numbering; we would have a 4th wk_10 each month which is PI*d_10 long.

In the above scheme, we still have a 0.41592654 week at the end of each year; but at least, this is only once per year, and can be mapped to new year's festivities.

This is a deficiency which we cannot quite overcome without altering the SI second; I think physicist all over the world should consider changing the second in the next SI revision to PI current seconds.

Success!

But still, we have reached our goal perfectly:

• Our system is based only on clean metric steps.
• Just once we have to take into account the factor PI to compensate for nature; something mathematicians and physicists are well used to.
• We are constantly reminded about the irrationality of time, every year's end; the irrational week can be used for partying, and who would want a rational party anyway?
• And, to do even better, we have 15% more time each day, and half of the week off!
