I think that would undermine the utility of anything called "current-seconds".

Is a chair finely made tragic or comic? Is the          John Cowan
portrait of Mona Lisa good if I desire to see           cowan@ccil.org
it? Is the bust of Sir Philip Crampton lyrical,         http://ccil.org/~cowan
epical or dramatic?  If a man hacking in fury
at a block of wood make there an image of a cow,
is that image a work of art? If not, why not?               --Stephen Dedalus
