Hi Severin Does the time also revert to 1907, or 1940 or something like that? If so, then I wouldn't be surprised if it's the little internal battery. If it hasn't been replace for a while (3-5 years) then that can do strange things to do with startup as well. That's normally one of the easiest things to replace to test,..and the cheapest. :o) (Well one of the cheapest).
Depending if it's a slot load or a tray load, you can refine the google search for "changing battery in an iMac G3" to "changing battery in an iMac G3 slot/tray load" depending on which it is :o) <http://www.google.com/search?client=safari&rls=en-us&q=changing+battery+in+ iMac+G3&ie=UTF-8&oe=UTF-8> Hope that helps.
