<p><P>PROBLEM TO BE SOLVED: To provide a time monitoring device capable of preventing unjust time correction at low cost, an electronic device, a program, and a time monitoring method. <P>SOLUTION: The time monitoring device 10 has a storage section 11 for storing an accumulated difference value 15 which is the accumulation of the differences between set times and current times, and an allowed difference value 16 representing a tolerance for the accumulated value difference 15, and a processor 12 for executing the procedures of a monitor control section 14 which acquires the current time from a clock, when the control section receives a set time by a monitor request issued following time correction; calculates the difference between the set time and the current time, adds the calculated difference to the accumulated difference value 15; and compares the added accumulated difference value 15 with the allowed difference value 16, to determine whether to perform time correction. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
