$ scheduled-reboot --help
USAGE: scheduled-reboot --time=<HH:MM> --dow=<value> --check_intvl=<value>
 
 Creating a reboot scheduling plan
 --time=<HH:MM>: Time of day to reboot
 --dow=<value>: Comma separated list of days-of-week starting with 0
 e.g. "1" only on Mo
 "0,1,2,3,4,5,6" daily
 "0,2,4,6" Su,Tu,Th,Sa
 
 --check-intvl=<value>: 0 Means no check for any active call - reboot is executed as planned.
 --check-intvl=<value>: >0 Means how often an outstanding reboot call is suppressed if an call is active
 on that device and adding a delay of 5 min before next check-interval.
 When reaching the maximum check_intvl iteration while a call is still active, the
 current reboot job is skipped and shifted to the next reboot-job execution based
 on the scheduling plan. Default value is 0 -> no check.
