[Qgis-developer] ogr virtual datasource not working

[Milo van der Linden]

One more question. I have now created the following vrt, but the DateTime is
not parsed correctly. Are extra options available for the datetime object to
tell ogr how it is formatted and thus, how it should be interpreted?

<OGRVRTDataSource>
    <OGRVRTLayer name="test">
        <SrcDataSource relativeToVRT="1">test.csv</SrcDataSource>
        <GeometryType>wkbPoint</GeometryType>
        <LayerSRS>EPSG:28992</LayerSRS>
        <GeometryField encoding="PointFromColumns" x="T X Coord Loc" y="T Y
Coord Loc"/>
    <Field name="Incident Id" type="Integer" />
    <Field name="Nr Incident" type="Integer" />
    <Field name="Dtg Start Incident" type="DateTime" />
    <Field name="Dtg Einde Incident" type="DateTime" />
    <Field name="Brw Melding Cl" type="String" />
    <Field name="Brw Melding Cl1" type="String" />
    <Field name="Brw Melding Cl2" type="String" />
    <Field name="Naam Locatie1" type="String" />
    <Field name="Postcode4pp" type="String" />
    <Field name="Plaats Naam" type="String" />
    <Field name="Gemeente Naam" type="String" />
    </OGRVRTLayer>
</OGRVRTDataSource>
