ssprocessds.hhpickup.Rows.Clear();
 ssprocessds.ReadXml(f.FullName);

At the client site, when I read 2013-10-24T00:00:00-04:00 from the .xml file ( I don't know how to show the xmlhere)
the result in the datetime column of the datatable was 2013-10-23:09:00.

It worked fine on my site.
I was testing at about 1PM ET.
I noticed that time on the client machine was 3 hrs behind me because the Time Zone was Pacific.
I changed the time zone on the client machine and got the correct date when reading the xml.
Does anyone know why a time zone should push a date back a day in the middle of the day?
Also, why would readxml mess with a date at all?
