I support that ! This is the feature I miss the most in DDG. Most of my searches during the day relate to tech stuff, and recent content is one of the most relevant criteria (usually, I filter to get the result from the last 12 months).
Thx! This is something we've wanted to do, but don't have great data for yet. If you use the sort by date feature (for timely pages) there is a date displayed. You can get to that by selecting it in the drop down next to the search box or by typing sort:date or just s:d at the end of the query.
You can also quickly get to the google ranges (when needed) via our !bang syntax: http://duckduckgo.com/bang.html - e.g. just add !gyear !gmonth etc to the end of your query.
