For 1.6.2 rc2, commit: 30b8d9378b8260e452552b806610dc9b6fe0b69f, database value for elapsed_time for some tasks doesn't match the value from the stats file:

sqlite> select * from orm_task where id=3649;
          build_id = 1
    work_directory = 
         cpu_usage = 5
     task_executed = 1
           disk_io = 52
       line_number = 0
path_to_sstate_obj = 20/sstate:xproto::7.0.25:r0::3:203a1756558b013be7bb0944cf96eb81_populate_lic.tgz
   sstate_checksum = 203a1756558b013be7bb0944cf96eb81
        source_url = 
             order = 1840
      elapsed_time = 0.63

         recipe_id = 316
         task_name = do_populate_lic
           message = recipe xproto-1_7.0.25-r0: task do_populate_lic: Succeeded
           outcome = 0
                id = 3649
     sstate_result = 1
       script_type = 2

$ cat core-image-sato-qemux86/201411171101/xproto-1_7.0.25-r0/do_populate_lic | grep Elaps
xproto-1_7.0.25-r0: do_populate_lic: Elapsed time: 0.44 seconds
