I'cant tell you exact solution but for example like that (server involved solution):

1. Implement server action that returns download time by download id. Let's say domain.ext/getdownloadtime?id=39994884
2. When download is requested from client, store download identity inside user session on the server (this should be implemented as List if user can have multiple downloads at time).
3. When download is finished on clients side request server action (getdownloadtime) with id according to recently finished download. You can do it with javascript background request. When server returns download time just display it as you want.
