Parameters:

reverse - is set to true if the traversal starts at the 'to' end of the edge and stops at the 'from' end, this can only happen if the edge is undirected.

getEdgeTime

public double getEdgeTime(EdgeI edge,
                          boolean isReverse)

Always returns 'edge.getTime(isReverse)'.
