No, thats not possible
# rdate -o 123 -nvv 0.debian.pool.ntp.org
rdate: Could not set time of day: Invalid argument
It's debian bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=502336
I installed ntpdate and it worked fine.
I got it from emdebian, but it shouldn't matter.http://www.emdebian.org/grip/search.php?package=ntpdate&arch=&distro=sid
Download the .deb. You also have to download ALL the debs of the dependencies. (And I did dependencies of dependencies to be safe.)
This has to be done at root (/)
wget the .deb file.
Then: ar vx [the deb file]
This will create a data.tar.gz.
Then: tar xzvf data.tar.gz
This will extract all of the files where they should be.
Delete the files that ar extracted and do it again for all the debs.

And.... drum roll....
As more people start getting these with the date being farther and father in the past, I imagine that this will be a growing problem. Another thing that might work is an ntpdate in ubuntu before you attempt the debian install, if the rtc maintains over reboots (which it should) then this should work.
