If anything, much of the above goes to show that when it comes to timelines that most witnesses cannot be precise. To take this to the extreme, at least one waiter is recorded as stating that the alarm was raised as early as 9.30pm. We know this was an impossibility when we look at the vast majority of the other statements. One more reason why a reconstruction should have been undertaken within days.
What is clear is that 10pm was by no means the agreed time;

http://www.mccannpjfiles.co.uk/PJ/BAREND_WEIJDOM.htmAt 21H20, Executive Chef A. E. G. F. P. heard some clamour, which made him leave toward the restaurant, a few meters away, and was then informed that a child had disappeared.
At around 21:40, he left the restaurant passing through the same esplanade where moments before, he had seen the same table occupied by the three couples, empty, who had left in the meanwhile various items, principally clothing. He was told by his colleagues that the child who had disappeared was a child of one of those couples;
Property manager B. J. J. W. heard about the news being investigated on the evening of 3rd May at about 21.30 - 21.40 from P.B., a Dutchman and owner of the Atlantico restaurant, who passed by the witness near the Baptista supermarket, in P da L and who asked for his help in searching for Madeleine. He then went to the place where the events occurred which was at about 21.45 - 21.50.
Dinner finished at around 21H45 and some minutes passed where waiter R. A.E D. L. O. looked towards the table but saw no one - his colleague told him that all the guests of that table left rapidly and abruptly. He remembers having heard shouts in the direction of the McCann apartment;
