Been having some "issues" trying to serialize datetime fields from infopath to SQL2005. The problem lies in the serialization expects a fully qualified datetime value including locale e.g. 2006-09-20T01:56:45+10:00. However, Infopath, and XML in general doesn't record the local e.g. 2006-09-20T01:56:45
So after doing some searching i came across the adjust-dateTime-to-timezone function for xsl V2.0. So to change a datetime to a sql2005 date do the following:
Which works great until you use the .net XslCompiledTransform class. Unfortunatly it only supports V1.0 so doesn't recognise the adjust-dateTime-to-timezone.
So my dodge workaround for the moment is to add the timezone onto the end "manually". When I work out a better way to do this, i'll write it up.
