Hi Richard,
I figured out what you did. Not exactly what I am after. College had
a suggestion. I am going to work on adjusting the structure to storing
time/date as BIGINT and do the math on that. I need to be able to adjust the
interval as needed (depending on user request) and not have it fixed to
position in a string.
Thanks,
Andrew S

Hi Richard,
That gave me 10 hour intervals not 10 minute. Which is the part that
controls the frequency?
Thanks,
Andrew S.

Maybe this:
SELECT substr(dateTime,1,12)||'0:00:00', avg(date)
FROM dataStreamRecord
WHERE fwParameterID=1074
AND dateTime BETWEEN '2015-11-17' AND '2015-11-18'
GROUP BY substr(dateTime,1,12)
ORDER BY 1;
