Elaborately discusses the treatment of the time isolates of Colon Classification (CC), 7th edition in the automatic environment. From the very beginning CC has separately specified isolate numbers for time, which is one of the five fundamental categories. As the time isolates can appear with any one of the Main Classes enlisted in the schedule of basic subjects, the schedule for time isolates is mentioned as a common schedule. This research paper describes the importance of time (i.e. Meteorological time, Civil time, etc.) in classifying the thought content of any document. It also discusses the structure of the schedule of the Common Time Isolates including all divisions and subdivisions. Discusses the rules of expert systems developed using Prolog to handle the procedure of picking up numbers from other schedules and forming the special components to build compound time isolates. Describes the procedure of developing knowledge base in respect of time isolates. Some special techniques of defining lexical knowledge regarding time isolates are also discussed. Working procedure of different program segment of inference engine is illustrated. Includes the scope of forming compound time isolates according to CC7. Illustrates the specific techniques used for different groups to follow the instruction of the schedule.
