Claim:
A job management apparatus for managing job information, comprising: a first obtaining unit configured to obtain, from a client apparatus via a network, first job log information corresponding to a job generated by the client apparatus through processing starting at a start time and ending at an end time and transmitted to an image processing apparatus at a transmission time, the first job log information including the start time and the end time, the end time including the transmission time; a second obtaining unit configured to obtain, from the image processing apparatus via the network, second job log information corresponding to the job transmitted from the client apparatus and executed by the image processing apparatus through processing starting at a printing start time and ending at a printing end time, the second job log information including the printing start time and the printing end time, the printing end time including a sheet ejection time in the image processing apparatus; and a generation unit configured to generate a final log corresponding to the job based on the first job log information obtained by said first obtaining unit and the second job log information obtained by said second obtaining unit when identification information included in the first job log information is identical to identification information included in the second job log information, wherein said generation unit comprises: a start time comparison unit configured to compare the start time included in the first job log information and the print start time included in the second job information; a start time setting unit configured to set an earlier one of the start times compared by said start time comparison unit as a final start time of the job in the final log; an end time comparison unit configured to compare the end time included in the first job information and the print end time included in the second job information; and an end time setting unit configured to set a later one of the end times compared by said end time comparison unit as a final end time of the job in the final log, wherein, when the identification information included in the first job log information is identical to the identification information included in the second job log information, it is determined that the first and second job log information is provided for the same job.
