Derod full node warnings

I’ve been getting several warnings recently of the sort:

WARN[253442] Block timestamp is  less than its parent, rejecting block

Should this concern me? My system time is on part with an ntp server. I use dero-wallet-cli and CMD with this instance of derod and don’t want there to be any lost transactions on my node.

Thanks!

Please ignore this warning if your time is synced.
Use following cmd in linux to sync your machine time:
ntpdate pool.ntp.org

right on. thank you.
