report of most common crashes "today" tracks calendar days, becomes useless when the clock rolls over

The main report on errors.ubuntu.com shows most common problems in the past day; but this isn't a rolling 24-hour window, it's problems reported in the current calendar day. So currently, at 5:42am UTC, I'm seeing roughly a quarter of the crashes that I was seeing earlier in the day (local time).

I think the top-level report should show stats either for the most recent full calendar day, or for the last 24 hours. The latter would be preferred but I realize it may be a lot harder to get that data. The former would have the downside of always being out of date - but being a day out of date is generally less of a problem then not having enough data in the report.
