Depends on usage I suppose. Gmail for example doesn't use yesterday for emails. One use I'm thinking of for this is in the jpkg status message that says how long ago it was since you updated your local JAL catalogue, in that case I think it is the time duration, rather than whether it was yesterday that is important.
