[Zope] Zope 2.7 and scheduling

Hello, I have a product based on Xron that runs nicely under Zope-2.6.x. Now Xron doens't work under 2.7 so I guess that's why my program isn't either. I have googled for other schedule programs working with Zope-2.7 and found ZopeScheduler. Now while I can find ZopeScheduler in the collective cvs repository, it is impossible to find TimerService anywhere (which ZopeScheduler depends on). All the stuff should be found at http://dev.legco.biz but that website is down :-(( Is the project discontinued or moved to some other website? I really need some schedule stuff in Zope. Greetings, Gitte Wange
