Kind of a sad moment, but I'm glad Tim was able to pass the project along. Too many times a project just dies on the vine. I can't imagine how relatively painful moment must have been to get to where it is, and how much work it is. Date-time logic is some of the most difficult to get right, especially when you add in various locals and options.
Just today, I've been working around issues by replacing a bunch of custom logic with moment.
