Mike the timeline hasn't changed....except for the one at 9:10 by JT the time its self hasn't changed but the man she saw has...he has now been identified. 
Hi Patti,
I do not necessarily agree that Jane Tanner saw what she claimed she saw...
But, she could have known that the crèche was in use of an evening, and that at a particular time in the evening, a parent usually collected their child, and walked back to their apartment, across the crucial road junction, which Tanner sought or seeks to maintain the man carrying the child walked across...
Of course, put yourself in that mans shoes, he has been to the evening crèche, to collect his child in keeping with his normal practice. As he approaches the junction and before he walks across it carrying his child, surely he looks right into the junction to make sure that there is no oncoming traffic, and if the man had done that, no doubt he would have seen Jane Tanner walking up the hill close to the road junction, the man would also have noted the presence of Gerry McCann and Mr Wilkes, but the big question is, did he...
Gerry and Wilkes do not see Tanner, but did the man see Tanner and Gerry McCann/Wilkes?
I think not...
