KDE Clock

Hi, I've noticed two things about the KDE clock on my system. First, it had set itself to PDT and picked, it seems, a time at random. When I went in and changed the clock settings through it, suddenty my mouse was unable to click and drag on windows. I logged out and logged in again and all was good. Today when I came in, the clockl had reset itself to PDT. When I changed it, once again my mouse was weird. Anyone else have this problem? Thanks, Nick
