Sorry if this has already been covered/found.
Struck a small problem using wwAsyncWebRequest (4.68) and the saving of datetime values. Looks like the "msxml2.domdocument" saves the AM/PM portion as a.m./p.m. so when we come to get that value the CTOT() returns an empty time in wwXMLState.GetProperty().
I have subclassed this method and added a couple of strtran()'s to get back to AM/PM and all works well.
Hope this helps
Cheers
