Is there anywhere European movie database with production time of every movie? It seems logical it has to exist in order to keep legal ages of actresses.

European producers are not under the same American restrictions of the US 2257 code, and are not obligated to indicate date of production, unless of course the movie is picked up and released in the USA by a local distribution company (Private, Pink'o, VMD, etc).
That's why release dates of european movies are often difficult to pin down (just scroll down the EGAFD database titles and you will see what I mean).
And it meakes it easier for the producer/distrisbutor to avoid telling you that a movie is 5-10-15 years old, by occasionally repackaging the movie with new title(s) and cover art.
But I have occasionally noted that the Orgazmik site have "release" dates in their title database that often reflect when German version was released there. Everywhere else where you see a release date is a guessing game and should be highly suspect.
