Here's the select output by the query causing the problem. It looks
exactly how I would right it. So it must be right. :-)
It seems to me that this new parse_datetime is broken. The data sure
doesn't look corrupt, and I can see how the old logic would work just fine
on the data I printed.
SELECT useinfo.sid, COUNT(useinfo.id), MAX(useinfo.timestamp) FROM useinfo
WHERE (useinfo.course_id = 'devcourse') GROUP BY useinfo.sid ORDER BY
COUNT(useinfo.id);
