Unfortunately, this onset of awareness has come very late in the day, perhaps even too late.

Unfortunately, this inspired policy comes too late, far too late.

But tomorrow will be too late.

Unfortunately it was closed too late.

That is better late than never.

We should like to show our solidarity with the family and friends of the deceased.

We depart from that principle at our peril and here we clearly have departed from it.

For example   'the train has departed'   is what we say when we arrive late.
