I think you're probably onto something there, Isarra. :) (I hate the 12 a.m./p.m. confusion.) The Combined Communications Electronics Board at least at one point recommended avoiding 0000 because of its potential to confuse - see http://jcs.dtic.mil/j6/cceb/acps/acp121/ACP121I.pdf, section 327 (page 25 of the pdf).
