At what time did the scourging at the pillar take place on Good Friday? I have read some of the post on the accounts that took place between the time of the last supper through the crucifixion hour including the trials.
what time would the scourging at the pillar taken place?
The scourging of Jesus happened immediately after Barabbas had been released, so it would have been about 7 or 8 am on Friday morning. 

When harmonizing between the book of John, and the synoptic gospels, it is necessary to bare in mind that John used 'Roman time' and the others used 'Jewish time.'  So, the following references show "the 6th hour" (roman) as 6am, and "the 3rd hour" (jewish) as 9 am.

FRI 6 am: Pilate’s decision:


  It was about the sixth hour. He said to the Jews, "Behold your
  King!" They cried out, "Away with him, away with him, crucify him!"
  Pilate said to them, "Shall I crucify your King?" The chief priests
  answered, "We have no king but Caesar." So he delivered him over to
  them to be crucified. (John 19:13-16)


FRI 7:30 am (approx): Jesus scourged:


  So Pilate, wishing to satisfy the crowd, released for them Barabbas,
  and having scourged Jesus, he delivered him to be crucified. (Mark
  15:15)


FRI 9 am: Jesus crucified:


  And it was the third hour when they crucified him. (Mk 15:25)
