I think it was New Scientist.  It was mostly relevant for the really
long half-lifes, millions of years etc.  If I remember right, they
chose some definition of how long a year was and then ran into
trouble using "myr" or "ma" or some other abbreviation in a manner
that now conflicted with existing use.
