The following example, which assumes that the time is 5 PM (17:00), illustrates
three different ways to request the system to reboot in two hours:
user@host> request system reboot at +120
user@host> request system reboot in 120
user@host> request system reboot at 19:00
user@host> request system reboot at now
To reboot the system at 1:20 AM, enter the following command. Because 1:20 AM is
the next day, you must specify the absolute time.
user@host> request system reboot at 06060120
request system reboot at 120
Reboot the system at 120? [yes,no] (no) yes
