Before the date was taken on the destination files, since they are generated in the right order, lists based on last modified date were right but with the wrong date. Now rivet creates another list during the creation of the main object list just for storing dates of the source files. There is a 1:1 correspondance between the files in the objlist and the dates in the objdate lists so they can be retrived with the same counter. Another change is that now shortened dates are displayed in the index link list.
