Time stamp generating system

A time stamp generating system comprising:

• a time distribution server for generating time data depending on time point;
• and
• a user PC for holding time certification objective data,
• wherein said time distribution server generates time data corresponding to a time point and distributes said time data;
• and
• said user PC calculates time stamp generating data by using said time certification objective data as an input, acquires the time data generated by said time distribution server, and processes said time data on the basis of said time stamp generating data to obtain a time stamp.
