Since a few days my MacBook Air 2020 shows the wrong date when set to "Set date and time automatically". This is regardless of the chosen NTP server.
When time set manually, querying a NTP server from the command line returns:
$ sudo sntp -sS pool.ntp.org -9.789671 +/- 0.018845 pool.ntp.org 126.96.36.199
Which does not show date and time, but also no major offset.
The offset is consistent at 5 months, 2 days, 3 hours and 10 minutes.
pool.ntp.org. No luck.
- Tried different time zones. No luck.
- Tried VPN to fake a different physical location. No luck.
- Changed WiFi networks, including using my phone as hotspot. No luck.
- NVRAM reset didn't help. No luck.
It somehow got fixed when I installed
sntp via homebrew and ran it in combination. After running
sudo touch /var/db/ntp-kod sudo chown root:wheel /var/db/ntp-kod
