obtaining a modified time regarding a modification of the kept time; determining whether a predetermined condition is satisfied, the predetermined condition being a condition for determining whether there is a possibility that the modified time is before the recorded time associated with latest data recorded in the recorder; and in response to determining that the predetermined condition is satisfied, associating the time in which the kept time is not modified based on the modified time with data recorded after the latest data as the recorded time. ### Claim 10 (depends on 9) The time setting control method according to claim 9, wherein the predetermined condition includes a condition that the modified time is before the recorded time associated with the latest data. ### Claim 11 (depends on 9) The time setting control method according to claim 9, wherein the predetermined condition includes a condition that the modified time is before the kept time. ### Claim 12 (depends on 9) The time setting control method according to claim 9, wherein the predetermined condition includes a condition that a point at which the determining is performed is from when first data is obtained after operation of a recording apparatus starts in response to an action received by a switch to when the operation stops, the switch being a switch that receives the action regarding switching of on and off of the operation of the recording apparatus, and the recording apparatus including the recorder. ### Claim 13 (depends on 9) The time setting control method according to claim 9, wherein the predetermined condition includes a condition that (i) the modified time is before the kept time and (ii) a point at which the determining is performed is from when first data is obtained after operation of a recording apparatus starts in response to an action received by a switch to when the operation stops, the switch being a switch that receives the action regarding switching of on and off of the operation of the recording apparatus, and the recording apparatus including the recorder. ### Claim 14 (depends on 9) The time setting control method according to claim 9, wherein the modified time is obtained from outside via a communicator, and the method further comprises obtaining an amount of time required for communication with a source of transmission of the modified time, and correcting the modified time with the amount of time required for the communication. ### Claim 15 A non-transitory computer-readable storage medium storing a program executable by a computer to control the computer to perform processes comprising: associating a time at a timing that data is recorded in a recorder that records the data with the data as a recorded time, the time being based on a kept time kept by a timekeeper; obtaining a modified time including a modification of the kept time; and in a situation that it is determined that a predetermined condition is satisfied, the predetermined condition being a condition for determining whether there is a possibility that the modified time is before the recorded time associated with latest data recorded in the recorder, associating the time in which the kept time is not modified based on the modified time with data recorded thereafter after the latest data as the recorded time. ### Claim 16 (depends on 15) The storage medium according to claim 15, wherein the predetermined condition includes a condition that the modified time is before the recorded time associated with the latest data. ### Claim 17 (depends on 15) The storage medium according to claim 15, wherein the predetermined condition includes a condition that the modified time is before the kept time. ### Claim 18 (depends on 15) The storage medium according to claim 15, wherein the predetermined condition includes a condition that a point at which it is determined whether the predetermined condition is satisfied is from when first data is obtained after operation of a recording apparatus starts in response to an action received by a switch to when the operation stops, the switch being a switch that receives the action regarding switching of on and off of the operation of the recording apparatus, and the recording apparatus including the recorder and the computer. ### Claim 19 (depends on 15) The storage medium according to claim 15, wherein the predetermined condition includes a condition that (i) the modified time is before the kept time and (ii) a point at which it is determined whether the predetermined condition is satisfied is from when first data is obtained after operation of a recording apparatus starts in response to an action received by a switch to when the operation stops, the switch being a switch that receives the action regarding switching of on and off of the operation of the recording apparatus, and the recording apparatus including the recorder and the computer. ### Claim 20 (depends on 15) The storage medium according to claim 15, wherein the modified time is obtained from outside via a communicator, and the processes further comprise obtaining an amount of time required for communication with a source of transmission of the modified time, and correcting the modified time with the amount of time required for the communication.
