I need to to the fallowing: get the data from a dataset as an xml
(using GetXml() ) and the load it latr in another dataset (using
LoadXml)
My problem it that the datetime columns throw an exception when the xml
is loaded into the 2nd dataset(string was not ...).

My steps are:
store dataset1.getXml
Create the 2nd dataset (columns of the correct type, MappingType, etc)
dataset2.ReadXml(memorystream)

the actual schema exported by the 2 datasets is identical

Why exactly isn't this able to load my datetime columns correctly? (and
how exactly should fix this?
