Unless you're running it with additional configuration (e.g. the -g option), I don't think ntpd will save you from any bit flips other than the 10 least significant: You'll be outside the 1000s panic threshold.


Its not recommended to use ntpd with -g argument in production. An attacker can MITM NTP protocol. The 1000s threshold severely limits this attack. The attack can be used e.g. in defeating TOTP.

I'm not sure if this rogue bit can be used to attack TOTP. Can anyone clarify?
