Normally, it's just annoying. This time, I missed my bus because of it. My menubar clock was blissfully telling me it was "Tue 1:18:42 PM" - I just thought it was a particularly long day, since it felt later (it was a particularly long day, but that's another story).
So, I keep plugging away.
Eventually, I glance at the menu bar on my other computer. "Tue 4:24:15 PM" WHA? Crap. Missed my bus. But, my laptop still says "Tue 1:18:42 PM" Thanks, crashing menu bar clock. I'll be catching the next bus home...
At least it isn't blinking "Sun 12:00:00 AM"...
