Hi,
on all of my CentOS7 VMs on different hypervisors the config file e2fsck.conf contains the line
broken_system_clock = 1
I found this because on all of them, the root partition was not checked triggered by interval setting with tune2fs.
Do you see similiar /default/ settings on your machines? Is it an issue only on VMs? I have no CentOS7 host on bare metal to compare.
Thanks and cheers,
Gabriele
