Abstract

A communication device may perform to; in a case where a first event occurs in the communication device before a time and date measured by a time and date measuring unit is changed to a current time and date and the first event is a predetermined event, send specific log information to a server; in a case where the first event is an event different from the predetermined event, calculate first time and date information at a first timing that is after the time and date measured by the time and date measuring unit has been changed to the current time and date; and in a case where the first time and date information is calculated, send first log information to the server, the first log information indicating a log of the first event which is the event different from the predetermined event.

in a case where the first time and date information is calculated, send first log information to the server, the first log information indicating a log of the first event which is the event different from the predetermined event and including the calculated first time and date information.

2. The communication device as in claim 1, wherein

the computer-readable instructions, when executed by the processor, further cause the communication device to:

in the first case, store second time period information in the memory, the second time period information indicating the lapse of time measured by the time period measuring unit at the timing when the first event occurs;

in a case where the time and date measured by the time and date measuring unit is changed to the current time and date after the specific log information has been sent to the server, calculate second time and date information at a second timing that is after the time and date measured by the time and date measuring unit has been changed to the current time and date, the second time and date information indicating a time and date when the first event, which is the predetermined event, occurred, and the second time and date information being calculated by using the lapse of time indicated by the second time period information in the memory, a time and date measured at the second timing by the time and date measuring unit, and a lapse of time measured at the second timing by the time period measuring unit; and

in a case where the second time and date information is calculated, send second log information to the server, the second log information indicating a log of the first event which is the predetermined event and including the calculated second time and date information.

3. The communication device as in claim 1, wherein

the specific log information further includes third time period information indicating the lapse of time measured by the time period measuring unit at the timing when the first event occurs, and

the computer-readable instructions, when executed by the processor, further cause the communication device to:

in a case where the time and date measured by the time and date measuring unit is changed to the current time and date after the specific log information has been sent to the server, send reference information to an external device at a third timing that is after the time and date measured by the time and date measuring unit has been changed to the current time and date, the reference information being for calculating time and date information indicating a time and date when the first event occurred, and the reference information including a time and date measured at the third timing by the time and date measuring unit and a lapse of time measured at the third timing by the time period measuring unit.

4. The communication device as in claim 3, wherein

the specific log information further includes log identification information identifying the specific log information, and

the reference information further includes the log identification information.

5. The communication device as in claim 4, wherein

the lapse of time measured by the time period measuring unit is reset to zero every time the power of the communication device is turned on,

the computer-readable instructions, when executed by the processor, further cause the communication device to:

store time period identification information in the memory every time the power of the communication device is turned on, the time period identification information identifying a lapse of time measured by the time period measuring unit; and

in a case where the first event occurs during a time period from when specific time period identification information was stored in the memory due to the power of the communication device being turned on until when the power of the communication device is turned off, the log identification information includes the specific time period identification information.

6. The communication device as in claim 5, wherein

the computer-readable instructions, when executed by the processor, further cause the communication device to:

in a case where no event occurs in the communication device during a time period from when the time period identification information was stored in the memory until when the time and date measured by the time and date measuring unit is changed to the current time and date, delete the time period identification information from the memory.

7. The communication device as in claim 3, wherein

an electronic mail including the reference information is sent to the external device.

8. The communication device as in claim 3, wherein

the specific log information is sent to the server according to a Syslog protocol,

the first log information is sent to the server according to the Syslog protocol, and

the reference information is sent to the external device, which is the server, according to the Syslog protocol.

9. The communication device as in claim 1, wherein
