[Feature Request]: Migrate from ntpdate to ntpsec-ntpdate

### Which feature would you like to have?

ntpsec-ntpdate is a more secure implementation of ntpdate and all the distros already have this as default.

We could change the package installed during in prepare-host.sh to it without compromise usability and functionality.

### Funding
