<P>PROBLEM TO BE SOLVED: To check whether or not a format of an electronic form for input taken in an input terminal in the past is valid at that time. <P>SOLUTION: In this validity term confirmation method for the electronic form, a time correction value of a communication terminal is stuck to the electronic form taken in the communication terminal via a network and is stored, and confirmation is performed by the time correction value stuck to the electronic form. In the validity term confirmation method for the electronic form, the communication terminal periodically acquires standard time information from a standard time server via the network, calculates the time correction value with the communication terminal, pastes the time correction value to the electronic form downloaded from an electronic form distribution server and stores it in a storage part, reads the electronic form stored in the communication terminal at the time of data input and develops it on a screen, and confirms whether the electronic form is within a validity term recorded in the electronic form or not by time information of the communication terminal and the time correction value stuck to the electronic form. <P>COPYRIGHT: (C)2007,JPO&INPIT |
