Description

Adds my time server (time.xargs.org) to the list.

This NTP server has been a part of the ntppool project for at least a decade now. It is virtualized but keeps time ±20ms, ref its NTPPool page.

I've only set up NTS today, but it seems correct to my eyes:

$ openssl s_client -connect time.xargs.org:4460 -tlsextdebug -alpn 'ntske/1' -status < /dev/null
