As a native English speaker though, I hear "The time is finally come," much more frequently that "The time has finally come." Perhaps everyone I hear is just speaking quickly and I'm missing the "h" sound, but it's always seemed to me that "The time is come" was just some sort of set phrase.
Michael, I hope you reported it. "At last" should definitely be accepted. I reported it five months ago, londoncalling and pat presumably reported it five and four years ago, respectively. Still, nothing has been done; it is really most annoying. And yet, reporting it over and over is all we can do.
