From https://docs.ntpsec.org/latest/warp.html:

  > The NTP protocol will synchronize correctly, regardless of era, as long as the system clock is set initially within 68 years (a half-era) of the correct time

Which means 2036 will appear to work just fine, as 1970 is only 66 years away. Now jump forward to 2038, and this would not be the case..
