So I woke up to my husband telling me to check my computer clock, because it seems to have been reset...
Eh, whatt???
Well, he'd just turned his computer on, of course, and I was up late last night browsing (he was watching a horror movie). So this morning Gmail just sent my husband a message from me --- dated 1970!
Now you can see where this would be a problem after a long night watching horror movies, given that I wasn't born until half a dozen years later... and he was born even further along the timestream!
Turns out the leap year has Google very confused!
