The Globalization cultures contain the zero-based UTC date format "u". However, when parsing or formatting a date using this "u" format, a wrong date comes out. The local hours are not offset to the zero-based UTC format. End-users will see a wrong local date parsed from a UTC date, and a wrong UTC date formatted from a local date. Please add proper UTC support to Kendo UI.
The depicted issue was fixed with in the Q2'12 service pack release (2012.2.913) a couple of weeks ago. Commercial users can upgrade to this version, while the rest can obtain the fix with the Q3'12 release in mid November.
Thanks for entering this item Wannes. We'll evaluate adding formal UTC support in a future release. For others considering voting for this issue, here's a related forum thread: http://www.kendoui.com/forums/framework/globalization/kendo-fails-to-parse-or-format-utc-dates.aspx
