Detailed Description

TimeService Object Implementation.

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.

CosTime::UTO_ptr TAO_Time_Service_Server::secure_universal_time

(

void

)

[virtual]

This operation returns the current time in a UTO only if the time can be guaranteed to have been obtained securely. Currently this operation is not implemented and throws a CORBA::NO_IMPLEMENT exception, if called.

{
  throw CORBA::NO_IMPLEMENT ();
}

CosTime::UTO_ptr TAO_Time_Service_Server::universal_time

(

void

)

[virtual]

This operation returns the current system time and an estimate of inaccuracy in a UTO.
