Anybody else with similar?

Somebody's been messing with my laptop - altered the system date backwards.
What a merry jape....and I've a good idea who the culprit is.

No, don't do that, just stick a small post it note over the ball of his mouse and watch the fun as he unplugs it, goes to settings, reboots etc :D
