Let's talk in concrete terms. Could you propose an API for what you have in mind for the basic UTC functionality?
I'm not knowledgeable enough in Haskell to be able to propose a sensible API, but still..
although it will be able to do larger scale calendar calculations (i.e. adding days, months, etc.). Or maybe you provide the second-level calculations but document that they don't take into account leap seconds?
...that's the idea. A simple Calendar class with instances UTC, Gregorian/ISO, JD and/or MJD perhaps. Simple operations to add and substract periods, compare dates/times, convert between them, ask for miscellaneous info (leap year, day of week, etc.); with support for timezones (offsets from UTC) of course. That's all I've ever needed from a datetime library. As Peter Simmons has said, there are several libraries available for other languages which already implement a sensible set of operations for dates (boost has a good example). We should just borrow from them. /L/e/k/t/u
