Find keys with custom fields updated in period?Answered

We were thinking about the best way to handle this. We can't think of a case where this would be needed (and that you can't just create a custom license field containing either the date you last “changed” or the date in which things need to be re-changed). And then you can just search like usual using the advanced search in the LimeLM interface or the web API.

So, our default functionality already does what you're looking for.
