Happy to hear that the permission solved it. I'm not sure if the execute bit is enough for owner, as it is run as root, so I'd advise to just chmod +x /opt/timenowd/bin/powerbutton For timenow.conf, I noticed that on my device it didn't start without a longer sleep period, probably because proximityd hadn't yet completely started (I also had to add respawn 15 3 to proximityd as reported earlier by pierrem. Thus if it works for you, leave it as is. I will introduce the longer delay as well as fix the permission thing in lucky version 0.13 in a few days. I might ponder using sudoers instead of rootsh too, but as they say if it ain't broke... Happy new year and thanks.
