Service Interface Date Query

Question

Hi -
I am having trouble selecting records through a view object's service interface based upon specifying a date+time in the query.
I have a legacy table that has, among other fields, a DATE field. I create a view object on the table with a query (no entity object) and generate a service interface for the view. The web service interface works great for selecting on the non-date fields, e.g.:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body xmlns:ns1="/rt/model/common/types/">
<ns1:findContact>
<ns1:findCriteria xmlns:ns2="http://xmlns.oracle.com/adf/svc/types/">
<ns2:filter>
<ns2:group>
<ns2:item>
<ns2:attribute>ContactName</ns2:attribute>
<ns2:operator>=</ns2:operator>
<ns2:value>bobishisname</ns2:value>
</ns2:item>
</ns2:group>
</ns2:filter>
<ns2:findAttribute>ContactTime</ns2:findAttribute>
</ns1:findCriteria>
</ns1:findContact>
</soap:Body>
</soap:Envelope>
successfully returns the response data:
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"><env:Header/>
<env:Body>
<ns0:findLastCustomerContactResponse xmlns:ns0="/rt/model/common/types/">
<ns2:result xmlns:ns2="/rt/model/common/types/" xmlns:ns1="/rt/model/common/"
xmlns:ns0="http://xmlns.oracle.com/adf/svc/types/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns1:ContactSDO">
<ns1:ContactTime>2012-02-14T14:59:02.0-08:00</ns1:ContactTime>
</ns2:result>
</ns0:findContactResponse>
</env:Body>
</env:Envelope>
However, when I add the item to restrict the ContactTime, the time component is dropped, and only the date is used in the filter.
For example, this request payload does not return a result (ContactTime greater than 12pm on 2012-02-14):
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body xmlns:ns1="/rt/model/common/types/">
<ns1:findContact>
<ns1:findCriteria xmlns:ns2="http://xmlns.oracle.com/adf/svc/types/">
<ns2:filter>
<ns2:group>
<ns2:item>
<ns2:attribute>ContactTime</ns2:attribute>
<ns2:operator>></ns2:operator>
<ns2:value>2012-02-14T12:00:00.0-08:00</ns2:value>
</ns2:item>
</ns2:group>
</ns2:filter>
<ns2:findAttribute>ContactName</ns2:findAttribute>
</ns1:findCriteria>
</ns1:findContact>
</soap:Body>
</soap:Envelope>
However, this request payload (ContactTime greater than 2012-02-13) does:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body xmlns:ns1="/rt/model/common/types/">
<ns1:findContact>
<ns1:findCriteria xmlns:ns2="http://xmlns.oracle.com/adf/svc/types/">
<ns2:filter>
<ns2:group>
<ns2:item>
<ns2:attribute>ContactTime</ns2:attribute>
<ns2:operator>></ns2:operator>
<ns2:value>2012-02-13T12:00:00.0-08:00</ns2:value>
</ns2:item>
</ns2:group>
</ns2:filter>
<ns2:findAttribute>ContactName</ns2:findAttribute>
</ns1:findCriteria>
</ns1:findContact>
</soap:Body>
</soap:Envelope>
returns the record:
<ns1:ContactName>bobishisname</ns1:ContactName>
In the view object, I can set the attribute type on the ContactTime field to Timestamp, but it does not affect the behavior. I cannot modify the underlying table to change from DATE to TIMESTAMP.
How do I set up the view object so that the service interface correctly passes the time component to the database and execute the query correctly?

The select query is for fetching entry sheet number is:
select ebeln belnr bwart bewtp menge xblnr lfbnr mwskz shkzg srvpos packno from ekbe
        into corresponding fields of table it_ekbe
          for all entries in it_ekko
            where belnr in s_belnr
              and lfbnr in s_lfbnr
              and ebeln = it_ekko-ebeln
              and bwart = '101'
              and bewtp eq 'E'.      "for service acceptance no. (GR no.)
Here I have taken lfbnr as entry sheet number.
