<P>PROBLEM TO BE SOLVED: To provide a communication terminal capable of selecting a time server with high time accuracy as an acquisition destination of time information and not requiring a labor of a user. <P>SOLUTION: A communication terminal 100 sends a response request packet through a network 300 and receives a response packet accordingly sent from time servers 200-206. Then, the communication terminal 100 selects a candidate for an acquisition destination of time information from among the time servers 200-206 using data acquired from the response packet. There is a reference source identifier showing a reference source for time adjustment of the servers 200-206 in the data acquired from the response packet, and the candidate for the acquisition destination of the time information is selected based on the reference source identifier. <P>COPYRIGHT: (C)2012,JPO&INPIT |
