I'm not sure that I agree with this 100%.  I would think that the scourging of Our Lord and His crowning with thorns would have happened back to back, and I also don't believe an hour would have passed between when Our Lord commended His Spirit to the Father and His subsequent death.  I think this is just a pious reconstruction, and I doubt it's completely accurate.  There's also no time allotted for when Our Lord would have been kept in Caiaphas' dungeon.  I believe that He spent many hours there, in the stench, bound in a very uncomfortable position.

Perhaps Our Lord prayed in the Garden from 9 to midnight, was betrayed by Judas at midnight.  Then the events shown below from 1, 2, 3, 4, and 5 AM all happened between midnight and 1AM.  Then he spent from 1AM to 6 or 7AM in the dungeon, being taken to Pilate by 7 or 8AM, with the Scourging and Crowning with thorns happening within the same hour.
