Correct reversal of date/time and datavalue

The date/time and the datavalues were coming through reversed in the
xml.  It was simply pulling from the wrong column number.  Corrected
this.
Added Timezone to Date/Time

Added the time zone to the date/time value.  This information is
required, but not actually stored in our database at this time.  I am
assuming the data time zone is always EST at this point.
