Hmmm. *I* think it's a stupid marketing gag.
We allready have a worldtime. To be more exact we have quite a few
"universal times": UT0, UT1, UT2 and UTC.

In short: UTC is "our" time based on the physical definition of
1 second and UT0 is astronomical measured. UT1 and UT2 are UT0 with some
"corrections". IF UT1 and UTC differ by more than 0.7s we get a leap
second at the end of the year

If you're interested now, grab an astronomical encyclopaedia
and read about ET, TDT, TDB, TAI (...) as well  ;-).

Maybe this is possible as an additional timezone (with a lot of hacking
due to the strange representation: "@xxx").
