1) Could we call this "Earliest Next Retrieval"? "Earliest Retrieval" sounds like the time that it was first retrieved. Even more useful for the user would be the actual next retrieval (not earliest), but not sure how easy it is to get that info here.

2) Instead of showing an absolute time in a format like "2013-07-14 22:32:53.416221577 +0200 CEST", could we instead show it as a duration from `time.Now()`? I think it would be more readable and useful.
