Help! I can't rock out, with my clock out!

I need your help! Look at this:

One, two, one o'clock, three o'clock rock
Eight, six, three o'clock, two o'clock rock
Nine, seven, one o'clock, seven o'clock rock
We're gonna rock around the clock tonight

There's no way I can possibly rock to my maximum potential with a clock that's so obviously broken... What is causing the hours on my clock to be so messed up?


There are 24 hours in a day... and my clock is only a twelve hour clock.


There are 24 hours in the day, so each of the times could be indicating one of two possibilities:
1/13, 2/14, 1/13, 3/15, 8/20, 6/18, 3/15, 2/14, 9/21, 7/19, 1/13, 7/19
If we substitute each of these numbers with its corresponding letter in the alphabet (1 - A, 2 - B, 3 - C, ... , 24 - X), we get:
A/M, B/N, A/M, C/O, H/T, F/R, C/O, B/N, I/U, G/S, A/M, G/S
If we choose the correct letter from each couple, we will get the word "ANACHRONISMS".
