commit 4416c836d0e1456dc80e27c8fb17a95bd195f87c
Author: Jan Holesovsky <kendy at collabora.com>
Date:   Fri Jan 13 16:09:47 2017 +0100

    Log the time in wall-clock time, instead of since the process start.
    
    Otherwise we are getting completely confused times - various processes start
    at various times, so for one process the epoch start can be eg. 20 minutes
    later than for the other.
