DDG staff here. Thanks for sticking with us. The time/date filtering is being worked on - hopefully we can release it soon. That should make a lot of people happy. For quality of results, I'm biased but I've found they have improved thanks to a lot of feedback from users providing specific queries that could be investigated one-by-one. There's now a feedback button (desktop only) so if you're able to give more examples of bad results that will help improve further.
