Hah.. Wikipedia != no dispute...
But for this it's probably pretty safe.

Oohh. That's an area with a lot of discussion, and I think it came up on the list a few months back, with folks slinging "first references" back and forth.  Or maybe that was a discussion here at JPL.
Wikipedia, unusually, actually cites a NIST page. (of course, the link in the bibliography for HP AN 1289 by Allan, et al.,  is just to the Wikipedia entry for "Application Note".. Spare me!)

In any case, the solomonic solution of TLA (three letter abbreviation) which is not a TLA (Three Letter Acronym) is not too bad.  Look what happened with the meter and prime meridian a few centuries ago.  I guess we could have the Prime Meridian through Giza and use the Royal Cubit..
