That is something that NTP is not going to be able to survive!

It will not make the correction from 1975 to today except when it is
told to do so on startup.  When your server is not available on startup,
you are out of luck.

Of course with "normal" conditions, e.g. a powerfail bringing down
everything and clients booting a bit faster than the server, it will
work just fine because the client is still within the acceptable time
