compile step was interrupted (due to timeout?) and shown as

compile   ( 10 hrs 34 mins )
stdout 


but the build was terminated by 3 hours
Timing:
Create	2018-09-12 05:02 (JST)
Start	2018-09-12 05:04 (JST)
End	2018-09-12 08:04 (JST)
Pending	1 mins 36 secs
Execution	3 hrs


It seems compile step end time is current time, not at the end time of the build.
