If it were possible and you weren't killed in the process, I'd go back to 10 minutes before the big bang. That way I could get a recording of what the known universe was like before the singularity (suck it Einstein, Hawking and Penrose!) and get to witness the birth of the universe as it exists now.
Any other time would seem asinine to go to if this choice were available.
EDIT: Also, it would be a trip if either Stewie & Brian or the Guru of Time & Crono's gang were already there.
