Why don't we have one timezone covering the whole earth?
And instead changing the time work and other things happens depending on where you are. Would be easier to arrange meetings across the globe. Same thing applies to summertime. You may start work earlier if you want, but dont change the clocks!
I wouldn't mind. The fact there's summer and winter time, also proves this point to a degree. You'd just have to get use to the fact it's 2PM in the morning. But it would solve a lot of issues. Australia already has summed in december. No biggie.
