what's wrong with absolute time?

Ever wondered about this? It is [relatively] easy to see there is no absolute space [and easy to digest]!
What's wrong with assuming an absolute time ticking away in the background? Read this:

Why IQ tests are not predicter of success!

Feynman had an IQ of 123 and the guy with highest IQ is virtually unknown.

While I think IQ is broadly indicative, as an absolute number it is useless.

Someone with an IQ of around 70 is certainly deficient and people with above average IQ are in general intelligent etc.

Use of IQ as indicator of success in inverse way by people especially concering africans [and african americans] is completely racist and baseless.

Daylight saving time!

As if we didn't have enough of complexity in telling time already!

Look at this:

1 year - 365 or 366 days!
1 day - 24 hours
1 hour - 60 minute
1 minute - 60 seconds
1 second - 1000 milli seconds

No doubt all the children go nuts, when taught this! what is the relation between 365, 366, 24,60,60,10.

In US, also dates are in Month/day/year order! what kind of arrangement is this? To me day -> month-> year is logical.

Now to add more fun we have daylight saving time!
I hope now they don't decrease time between 12 to 1 from 60 to 30 minutes [lunch time] to boost economy!
