So as an attendee to IO, I got a 10.1 tab; only problem is it was using the European time zone and for whatever reason used my google account settings which told it to automatically pull down the time from the servers (which would then report an incorrect time due to the incorrect time zone). I guess there's some kind of bug in the settings for the tab as it's missing the option to turn off automatic time, so I was left with a tab that had the incorrect time and could not be set.
So I wrote an android app that manually over-rides the automatic time setting, and it worked like a charm. If anyone else out there is having this issue, I have an apk file on hand that you can use to unlock your tab's time. Just make a post here and I'll try and get back to you asap.
