Bijou,
For all kinds of information about BSG, check "The Kobol Files" at
www.battlestargalactica.com
It's located in the "Features" section and was compiled by John Larocque. There's a vast amount of information there. I think what you're looking for is in Section E10.
(I could have just as easily told you "a year" but, I thought you might want to check out the Archives for yourself
)
