I'm trying to determine what the default time zone is for an XML Schema dateTime, when it is not specific. The time zone portion at the end is optional and it may be omitted:
2013-01-11T16:02:55
I read in this answer that the time zone is undetermined when not specified. I read in the comments to this question that the default is UTC if not specified. I also read through the W3C definition and that didn't give me a clear answer.
Can any experts point me to where this is specified?
