Hi all,

I think this is one of those questions which has quite a few answers, but 
given a map, how do I replace the values by applying a function to those 
values, but only if they meet a condition?

I understand the building blocks of (map..), (filter..), (assoc-in..) and 
(filter..) and I can see how something could work using those pieces but is 
would be pretty verbose.  I am sure there is probably a much more simple 
way using a more abstract function.

The actual use case is I have a list of maps as returned from the 
clojure.java.jdbc framework and they contain timestamps.  I want to replace 
all the timestamps with (for example) to a Joda LocalDate using the 
excellent clj-time library.

Any pointers?

Thanks!

Col
