Abstract

In our modern clock-ruled culture, it is not too much to say that no society can exist unless based on “time”. Computers, which are the key device of an information society, are equipped with high precision clocks to synchronize their entire circuit function. In an electronic environment or digital society built on computers, recordkeeping relates inevitably to the time that is ticked away by the clocks embedded in the computers. Time is thus the infrastructure of this information society.  To save the situation, a notion of time for the digital society should be properly defined and popularized, specifying the way and conditions of using it safely. The scope of discussion here focuses on some specific industries and applications for time-stamping technologies.   The study here presented in Chapter 5 will be further refined step by step as their validity is verified in actual use. Meanwhile, authors are planning to work on this study for standard time distribution, which is as important as time-stamp to time business.
