"... there appears to be a rift in the space-time continuum ..."
Sorry, got a little wierd there (probably not enough coffee in me yet)
Anyways... network time tells you its 1916, and blackberry thinks its 2029?
First things first is find your setup icon, and run through that. Make sure you've got the correct timezone selected. save that, and then do a battery pull.
Or if your computer is showing the correct date/time, then syncing you berry should also match your berry's time to the computer.
Any other info you can give to help others assist you?
