As of Kernel-cmm.671 Timespans created in the context of an offset will start in that offset, and when no context is available the defaultOffset for a Timespan will be zero. This affects a TimeStamp created from a string representation of itself, which will now have zero offset (UTC). Update TimeStampTest to reflect to this behavior.
