package GNAT.Sockets.NTP is
--
-- Get_Time -- Quyery time from an NTP server
--
--    Server  - The server name or IP address
--    Timeout - For the operation
--    Adjust  - Subtract half of roundtrip time
--
-- The returned  time is UTC.  If the local time  is required  it can be
-- obtained this way:
--
--    Get_Time ("time.nist.gov") + Duration (UTC_Time_Offset) * 60.0)
--
-- Returns :
--
--    The server time UTC
--
   function Get_Time
            (  Server  : String;
               Timeout : Timeval_Duration := 10.0;
               Adjust  : Boolean := True
            )  return Time;
