Time changes in log records

NethServer Version: 7.4.1708
I was digging in logs and I realized that time is changing at reboot. I mean the hours. No I’m not sure if is only at reboot, but I would like to stop this.
How can I do it?


The system time at boot is set from the BIOS clock, until NTP client receives the time from the network. I’d check the BIOS clock first.
