Proxmox RRDC update error

Have an issue with one of my customer Proxmox RRDC update error in thecluster with error below;

This is caused by drifting time on the host. Somehow the time use hwclock with wrong date.

To resolve the issue, need to update the time, the simplest way is sync with ntp using timedatectl.
Then delete /var/lib/rrdcached/db and restart rrdcache.service.

Thanks
