TTDS clock help

I got my ttds in the other day, but the time is 12hrs off. I tried looking through all the files, but couldn't find anything to adjust this. Any help?edit: nvm, had to go to the ds menu. Mod, please close.

It is in the DS settings.Turn on your DS without the TTDS card in it, then on the very bottom is an Icon for the options, there you can set the time and date.
