My to reflexion on stupidity of times zones

If there is 1 A.M in London shouldn't be say 4 P.M here or there.

Where is stated that work must starts at 8 AM not 4 PM (new time) ?

One world - One time for ALL



OK technically, I do not propose to lighten suddenly whole world at same time and switch the light off.
We just do start our working day accordingly to sun shine.
Additional advantage that when you say that you do start work at 4PM that describe your position on the globe instantly.
Similarly New Year celebration will start at same time everywhere, Champagne corks pop up all at ones , not whole 24 hours ! Some at night and some in the middle of the day !!
