@chewiebug can you comment on removing the date/tiemstamps from the javadocs? If you prefer to keep them I would maybe think a custom @created tag might be the way to go (there are different syntax). But I think this is task of git to keep track thats why I removed them from all touched comments (even if they do not triger doclint in some cases).

Hi Bernd,

I think, the creation information has mostly nostalgic value - some of
the classes were created way before the were committed to github. But I
don't think, they are a big loss, if we drop them.

Speaking of git keeping track of things: We might even throw out the
"author" tags. Blaming is best done with git as well.

Best regards,
Jörg

I have merge #125, which fixes this issue.

@ecki Thanks again!
