Fix issue with BuildEvent timestamp serialization If a custom build event does not implement a serialization method, the timestamp field may get serialized as an Unspecified kind. To fix this, EventArgs will now always serialize Utc format and not convert when observed. If the event kind is Unspecified, assume it's UTC and convert when the property is accessed.
