Err, an event is a particular set of coordinates (t,x,y,z) in 4D
spacetime. This is how it is used in GR, anyway.

An observer moment is a set of constraints, or equivalently
information known about the world (obviously at a moment of time). It
corresponds the the "state" vector \psi of quantum mechanics.

Perhaps you have different definitions of these terms, but it seems
like chalk and cheese to me.
