Thread:Extension talk:ChapTimeline/Can anyone post detailed instructions on how to install this extension?/reply (4)

The best I can offer is that I had to u/grade to SMW 1.9 and the latest zip file on the ChapTimeline repository before I got it to work - but it does work now. It is both consistent and reliable, though in need of enhancements and correction of a years/months/days anomaly on the bottom scale.
