Include creation date in documentation

"I wonder if it is possible to have Haddock include the date and time at which the documentation was generated. Ideally this should only occur on index.html, but to have it in any file (e.g. in the footer) would be OK, too. I couldn't find any information about dates in the documentation.

Documentation is created via Cabal:

cabal haddock --executables --hyperlink-source

Right now I include a token in the Cabal "description" field of the package, and sed-replace it afterwards, which is of course ugly."

I suggest this is a bad idea. It means the build result is different every time you run it. That's not good for dependency-based build systems.

I agree with Duncan here.
