Another tool for Timeline

I haven't had a chance to play with Timeline much recently, but I'm still holding out hopes that the Google Docs implementation (routed through Exhibit) will be what I need to make these tools available to my students.

Today I came across a website that uses a simple form for adding events to a Timeline, with the intent of using it as a calendar. It doesn't look like you can save this in any way and its scale (determined in days, rather than years) makes it much less useful for something like a survey course. In any case, it shows what might be possible to do if you knew more code than I do.
