If I open ResultsDB and hit Search, it contains 03/26/2019 - 04/24/2019 (Last 30 days) in the search form. However, that generates a URL like this:

https://taskotron.fedoraproject.org/resultsdb/results?&testcases=dist.rpmlint&since=2019-03-26,2019-04-24

which only shows results up to yesterday, because 2019-04-24 means 2019-04-24T0:00:00. If I change to URL to this:

https://taskotron.fedoraproject.org/resultsdb/results?&testcases=dist.rpmlint&since=2019-03-26,2019-04-24T23:59:59

then it works as expected.

Please adjust the search form to work as expected, i.e. 03/26/2019 - 04/24/2019 means from 03/26/2019 included to 04/24/2019 included. That can be either done by appending 23:59:59, or by bumping the date by one. Be careful to not break today search option. Thank you.
