When I do who -b; uptime I get

system boot  2021-10-12 17:05
 16:36:09 up 30 min,  1 user,  load average: 0.00, 0.00, 0.00

As you can see the boot time reported by the last command is ahead.
I have noted it is  one hour ahead after a reboot.

I have checked the system time in the BIOS  before booting Linux and it is correct.
