Orpheus cyber awards me 17 points for giving bad example.
they reach out to me to rectify if possible, anyway want to leave clear.
yours fallowing:

I've use csf - ConfigServer Firewall configuration to set within IPv4 Port Settings section,
option from
ICMP_TIMESTAMPDROP = 0
to
ICMP_TIMESTAMPDROP = 1

than tested this using custom ping
http://nping.online-domain-tools.com/

<ip address> --icmp --icmp-type timestamp

reply is:
