+ *
+ * @brief TimeService Object Implementation.
+ *
+ * The Object implementation implements methods to retrieve
+ * GLOBAL time as well as secure GLOBAL time. The times are
+ * retrieved as UTOs. The object also allows creation of a TIO
+ * for a given time interval.  In general, the TimeService clerk
+ * manages the UTOs and the TIOs. The notion of time returned
+ * here is the globally synchronized time.
