zaph0d, if you know the author please tell him to put a summary of the project in cliki, http://www.cliki.net/chronicity, that way automatic tools like asdf-install can see it.

Yes, I have told him. Thanks.

Hi mahmud,

Thanks for the tip. Chronicity is now asdf-installable.

I hadn't worked with asdf-install in such a long time, that I didn't even think about making Chronicity asdf-installable. But it was nice to find out that it actually can be installed with asdf-install.

Very good Chaitanya, welcome aboard yar! :-)

I don't mean to be a troll, but the fact that a simple function that has been available in other languages for years is only now making it to CL is a red flag for people considering learning Lisp.

what the hell? this is not "just coming to lisp", it's something someone wrote as a personal hack. I upvoted it and commented to encourage more lispers to post here.

Erik Naggum's essay on the subject is highly referenced and cited by people developing time and date libraries for other languages and systems:

The premiere text on time and date algorithms IS written in Common Lisp:

And here is a taste of what's out there;

  Yeah, like the Lisp Machine from 1980.
  Command: (software-type)
