When the issur de'oraisa begins is a machloqes tannaim (RH 28a-b): Rabbi
Yehudah holds starting from chatzos, R Meir - from sheqi'ah. (Does the
issur start from when the non-qorban <grin> could be shechted, or when
it could be eaten?) The Rambam in Chameitz uMatzah 1:8 pasqens chatzos,
as do we when we make the zeman 1 hour before chatzos (rather than 1
hour before sheqi'ah).

MiDerabbanan, it's pushed earlier, and that's the safety margin. But I
don't think that's enough to make it a morning mitzvah that it must be
done first thing.

Tir'u baTov!
