Refusing to cooperate with the rest of the world is not sane by my books.

Please add these lines to the datetime module's documentation. In some 
central, well lit place. I believe that if nothing else, the whole 
discussion should have proved to you that there are many people looking 
for them.

OTOH a sinceepoch(epoch=datetime(1970,1,1)) method of the datetime class 
should be equally easy. Would be especially useful if few of the more 
frequently used EPOCHs are provided as constants.
