This read-write integer configures how many seconds an outlet delays before powering off when a command requiring a turn-off delay is issued, with -1 meaning never power off and up to 7200 seconds of staggered delay available. Admins use it to shut equipment down in a controlled sequence, such as letting an application server finish flushing data before its storage array loses power. Setting a database server's outlet to a 45-second power-off delay gives its OS time to complete a graceful shutdown before power is actually cut.
