I still can't get it. I have the letters that I think are correct but have tried all the combinations of letters - to no avail. HELP!

This one is driving me nuts! I've tried so many combinations of letters and am not getting it. The time is 1:21:15 as on the hat, correct? Help! EDIT: I finally got it but it's not where I was going the whole time. SPOILER: It's NOT the time on Jim's hat. Use the numbers under the hint: 4,1,2,3,3,2,...
