On the other side, this brings the speed by using a binary search. I think a good improvement would also be to interpolate the binary search by storing the state of the previous match in the structure. Robert Hi,

I am viewing a graph that is three time zones off from mine. When I zoom, it zooms in three hours too early. The patch doesn’t work if you are in a different timezone than the data in the graph.
