I looked at my clock on my MB running 10.8.2 and it said 7:48pm, but it was 4:01am. The previous time was when I closed my MB. I had to click the time and open the clock preferences for it to update itself, which it did as I opened it. This is just an example of a few other performance issues with refreshing in other areas I am experiencing. I have repaired permissions to no avail. Can I get some further ideas of possibly clearing caches, other permissions to check, etc?
