Is it just me or do others often mis-read the a.m's and p.m's? I am so used to a 24hr clock that when I see, for example, 06.33 I automatically take it to be a.m, other than 18.33.
In the good old days, no self-respecting Harper fan would have been up before noon, so a 12 hour clock wouldn't need a.m. or p.m.. Aye lad, those were the days.
