Q. At this time of the year, I have a hard time davening after sunrise (Neitz Hachama) and coming on time to my job. Can I say brachos and korbanos before Alos Hashachar (dawn)?
A. Shulchan Aruch (O. H 47: 13) rules that Birchas Hatora as well as all the Birchos Hashachar can be recited even before dawn, excepting the brocho of Hanosein Lasechvi Bina, which cannot be said until dawn. Mishnah Berurah (31) adds that others also permit the recitation of this brocho at night. Shulchan Aruch adds that the parsha of the Korban Tamid should also be omitted. Mishna Berura (32) explains that this includes all the mishnayos on korbonos repited after, since this sacrifices were only done by day.
However, Mishna Berura (1: 17) rules that Parshas Hakiyor (washbasin) and Terumas Hadeshen (removal of the ashes) can be said at night. He adds that in need the Parshios of Korbanot could be recited at night too.
