Subject: Re: Dates (technical, not social...) From: Erik Naggum <erik@naggum.no> Date: 1997/03/31 Newsgroups: comp.lang.lisp Message-ID: <3068834505595900@naggum.no> * Bryan A. Bentz | I'm looking for some uniform mechanism to represent chronological dates, | including BC, potentially different calendars, etc. What I want to do is | to be able to enter events in these different systems, and reconcile them | on to one calendar (time line), in one system (that is, I don't need | something which will convert any date in any system to any other system). | | Before I write such a beast, might anyone out there have one? I'd | appreciate a direct reply, as my news server is really flaky. the Julian Date or Modified Julian Date system might be useful. JD counts in (fractional) days since some epoch a god-awful long way into the past. JD and MJD are used by astronomers. #\Erik -- I'm no longer young enough to know everything.
