You're right. It's seconds since shell was started. But if you set it, it starts counting from where you set it. In my .env file I have:
((SECONDS = $(date "+3600*%H+60*%M+%S") ))

and, gosh, I just figured that everyone does that! Smilie

Seriously, I did that so long ago that I forgot.

OPTIONS

       The following options are supported:

       --timeout SECONDS
		 Triggers  the recovery command action if the watchdog process is unable to connect to the NBD_DEVICE within the given timeout. If
