I'm currently working on the scheduling part of my application and I'm trying to use ranges like this: [from, to). This works fine besides for the dreaded 01.01.… 00:00 – 02.01.… 00:00 case. I'm not sure if there's anything specific in cldr, but I'd really like the option of having the option to format that as 01.01.… 00:00 – 01.01.… 24:00 instead. Even though it's technically the same the latter is seems more intuitive to read. Is that something you see you package to support?

Also I've seen cldr does have information about formatting intervals as well. I don't need it, but that might be a nice addition possibly after 1.0.
