Remove unnecessary code
Remove unnecessary code

The check for "this" performed in the case of "this quarter of an hour"
was copy/pasted in a large checkin.  The change it made to
daySpecified made no difference since the or in the later code
looked for an unspecified absolute hour.  I can come up with no
senseable phrase that matches the conditions and couldn't even
create a nonsensical phrase that made a difference.

Since all of the existing unit tests pass without this code,
I'm going to just remove it.
