I’ve switched back to the 24-hour notation on my main site, blog, and every other site I control. I’ve always been a fan of the 24-hour system, and the Canadian government encourages its use too. So… I figure doing a bit of mental math (like remembering that 00 is 12 a.m., 12 is 12 p.m., and subtracting 12 if the hour’s over 12) isn’t that hard, eh?
