1. Date: Sometimes there are multiple result rows with same date. example: there are couple results rows for 05-31-2016 at http://sc11e2411.us.oracle.com/cgi-bin/wiki_report/nightly-trends.py. Alex suggested it's because nightly execution starts as soon as the builds are finished and sometimes tests take longer, hence the date overlap.

We should incorporate some checks to make sure the date in the date column is unique.

2. Build: build column should also show the bundle date with build number. This will also be helpful in noticing nightly build failures early on
