Time information contained in a document file can be efficiently shared by persons. A time information communicating section (260) receives time information contained as content in a document file. An ID setting section (254) sets a time ID to the time information. A time information storage section (258) associates the time ID and the time information with each other and sends them. A time information communicating section (260) transmits the time ID. An alteration request communication section (262) receives time alteration information for altering the time information associated with the time ID. The time information communication section (260) receives time request information for inquiring the time information. A search section (256) detects the time information in response to the time request information from the time information storage section (258). The time information communicating section (260) transmits the detected time information to the sender of the time request information.
