I am using CentOS 7.5.1804 with GNU bash version 4.2.46(2)-release (x86_64-redhat-linux-gnu).
For scheduled reboots within maintenance windows I calculate the minutes from now up to the next reboot. In example, for an reboot in ~3 months I would use
shutdown -r +129600
Since interested in a better understanding of bash, I am curious about what could be the highest value and how to calculate it?
An scheduled shutdown with int32 would report
shutdown -r +4294967295 Shutdown scheduled for Tue 10184-07-27 ...
higher values are still possible, but how to calculate the possible maximum?
