quasihemidemisemicentury, on the other hand....(1/16 century, per wwh's definition) British musicians call an 8th note a "quaver". I undersatnd the terms for shorter notes (1/16th, 1/32nd, 1/64th, and 1/128th) are semiquaver, demisemiquaver, hemisimidemiquaver, and quasihemidemisemiquaver (whew). So the last would be 1/16th of a quaver.
(Edit: which fits right into our "time" subject.)
