  //    TimeService Object Implementation.
  //
  // = DESCRIPTION
  //    The Object implementation implements methods to retrieve
  //    current time as well as secure current time. The times are
  //    retrieved as UTOs. The object also allows creation of a TIO
  //    for a given time interval.  In general, the TimeService
  //    manages the UTOs and the TIOs. The notion of time returned
  //    here is the local time of the system.
