When (at what time of day) was Jesus crucified?
At the third hour	Sometime after the sixth hour
Mark 15:25 And it was the third hour, and they crucified him.	John 19:14-16 And it was the preparation of the passover, and about the sixth hour: and he saith unto the Jews, Behold your King! But they cried out, Away with him, away with him, crucify him. Pilate saith unto them, Shall I crucify your King? The chief priests answered, We have no king but Caesar. Then delivered he him therefore unto them to be crucified.
