Well personally I think the issue is whether you will use relative or 
absolute coordination.

We humans like to think we are the centre of the universe and that 
Greenwhich is that.

And then we try to use absolute coordinates.

I think if we ever became part of a space-faring society we'd realize 
that relative referencing is a lot more stable ;-).

(Or if we understood Einstein better :p).

IPv4 NAT is a form of relative, IPv6 without NAT is a form of absolute.

If you use relative referencing your system can easily be integrated 
into a bigger system, if you use absolute, it can't, but needs 
translations at ever border.

Not only does it need translations at every border, you also now need 
multiple addressing systems at the same time, or absolute at border 

It's a bit like using relative symlinks versus absolute ones.

Absolute ones break immediately and require chroots to keep functioning.

The "chroot" is equivalent to the "@border" address.

So the Linux people say: use UTC with timezone.

What if you don't know your timezone?
