Telling Time

Do you have trouble telling time I find it quite confusing, here are just a few things that I find quite amusing. I bought a 24 hour clock but found it had a flaw I took it back and told them it has no 24. At home I have a normal clock but I can't understand why the third hand on it is called the second hand. I am told the military tell time in differant ways midnight,s 2400 hours but that's a hundred days. Whoever thought up this idea his logic was reversed for no-one in their right mind would put the second first.
