I do get the same results - on my RS/6000. And I did not prepare the
test. But, to be more precise:

1. The failure does not indicate any problems w/ the HAVING clause.

2. This test will never work if there is a machine dependence on the
ability to resolve datatime down to the 1/100 second.

3. There appears to be something strange going on in the way GROUPed BY
datetime columns do not display the 1/100 portion of seconds. Is this a
known problem?

Unless someone objects, I will submit a test suit to, at least remove the
false reading on select_having.
