cosTime(3erl)			     Erlang Module Definition			    cosTime(3erl)

NAME
       cosTime - The main module of the cosTime application

DESCRIPTION
       To get access to the record definitions for the structures use:
       -include_lib("cosTime/include/*.hrl").

       This module contains the functions for starting and stopping the application.

       This  application  use  the  time base 15 october 1582 00:00 . Performing operations using
       other time bases will not yield correct result.

       The OMG CosTime specification defines the operation secure_universal_time . As of today we
       cannot  provide	this  functionality  considering the criteria demanded to fulfill the OMG
       specification.

       When using this application, time and inaccuracy supplied by the user  must  be	given  in
       number  of  100 nano seconds . The Time Displacement Factor is positive east of the merid-
       ian, while those to the west are negative.

       This application use calender:now_to_universal_time(Now)  to  create  a	UTC.  Hence,  the
       underlying OS must deliver a correct result when calling erlang:now() .

       When  determining  the inaccuracy of the system, the user should consider the way the time
       objects will be used. Communicating with other  ORB's,  add  a  substantial  overhead  and
       should be taken into consideration.

EXPORTS
       install_time() -> Return

	      Types  Return = ok | {'EXIT', Reason}

	      This operation installs the cosTime Time Service part application.

       uninstall_time() -> Return

	      Types  Return = ok | {'EXIT', Reason}

	      This operation uninstalls the cosTime Time Service part application.

       install_timerevent() -> Return

	      Types  Return = ok | {'EXIT', Reason}

	      This operation installs the cosTime Timer Event Service part application.

   Note:
       The  Timer  Event Service part requires Time Service part and cosEvent or the cosNotifica-
       tion application to be installed first.

       uninstall_timerevent() -> Return

	      Types  Return = ok | {'EXIT', Reason}

	      This operation uninstalls the cosTime Timer Event Service part application.

       start() -> Return

	      Types  Return = ok | {error, Reason}

	      This operation starts the cosTime application.

       stop() -> Return

	      Types  Return = ok | {error, Reason}

	      This operation stops the cosTime application.

       start_time_service(Tdf, Inaccuracy) -> Return

	      Types  Tdf = short()
		     Inaccuracy = ulonglong(), eq. #100 nano seconds
		     Return = ok | {'EXCEPTION', #'BAD_PARAM'{}}

	      This operation starts a Time Service server. Please note that  there  may  only  be
	      exactly  one  Time  Service  active at a time. The Inaccuracy parameter defines the
	      inaccuracy the underlying OS will introduce. Remember to take into account  latency
	      when passing time object between nodes.

       stop_time_service(TimeService) -> ok

	      Types  TimeService = #objref

	      This operation stops the Time Service object.

       start_timerevent_service(TimeService) -> ok

	      Types  TimeService = #objref

	      This operation starts a Timer Event Service server. Please note that there may only
	      be exactly one Timer Event Service per node active at a time.  The  supplied  Time-
	      Servcie  reference will be the object Timer Event Service contacts to get access to
	      a new UTC.

       stop_timerevent_service(TimerEventService) -> ok

	      Types  TimerEventService = #objref

	      This operation stops the Timer Event Service object.
