QueryBuilder: how can I specify the time along with the date in a query?

I and building a query (Eclipse client, 4.0.5) and I can set Creation Date after (including) and select the Specific Date from the calender picker.  I can also do the same for Creation Date before (including).

My query is ... how can I add the time?  For example, if I do after (including) April 22, 2014 and before (including) April 22,2014, if I look at the actual string in the Work Items view, it says:
Type is Task & Creation Date after (including) April 22, 2014 12:00 PM & Creation Date before (including) April 22, 2014 12:00 PM

In theory, that should be ONLY Task work items created EXACTLY @ 12:00 PM, right?  But it is not, because I get a list of them  with different times:
131217:Apr 22, 2014 11:56:24 AM
131220:Apr 22, 2014 3:23:52 PM
131221:Apr 22, 2014 4:01:51 PM

So how do I specify in the query builder the TIME to use?  Is there a way?  If not, then is the description in the Work Items view inaccurate?
