msdb..Sysjobhistory will tell you when a job completed.
You can see the job running by
select program_name from master..sysprocesses.
look in the results for something like
SQLAgent - TSQL JobStep (Job 0xE1F0E02DCF02B849AD3B42BF8B63A291 : Step 1)
There might be another place, trying running profiler to catch where and what is updated - watch master and msdb.
