Clock trivia, notice the display on clocks that use Roman numerals. It
goes I, II, III, IIII, IV, V, VI, VII, IX, X, XI, XII. Standard Roman
numerals denote IIII as IV. The Non-Standard application above is used to
keep symmetry in the display, keeping the character use in units of 4. (4
all Is, 4 with Vs, 4 with Xs) Not all clock with Roman numerals use this
system, but the use is widespread..


I've never seen a clock face with IIII AND IV on it.
