You may as well be, for all the work I've done on this in the past  
couple of years.

I'm quite happy, provided there is some sort of documentation, for the  
master branch
to change to the cldr branch.  I'm very happy with the dependency on  
local-time, having these two
systems playing nicely together is a great thing.

At a quick glance the only thing that i found noticeably missing was  
the ability to pass in
custom formatting strings to %format-date and format-date/gregorian- 
calendar.
Come to think of it, it would be nice to be able to pass these in to  
all the formatting functions.
