> The minTimestamp is calculated incorrectly to decide whether the journal can be used for the diff. The timestamp must be calculated from the root revisions of the node states to compare and not the revisions they were last modified. The last modified revision can potentially point very far into the past and result in a fall back to a more expensive diffManyChildren().
