Both olot and sh'lamim are brought at the time of matan torah, at the
end of parshat Mishpatim (Shemot 24:5). The gemara in Chagiga 6a refers
to both of these as being "lifnei hadibur". Rashi there explains that
this means that these were offered on the 5th of Sivan, and Hashem spoke
to us and gave us the Torah on the 6th of Sivan.
