Canonical Reaffirms Plans For Ubuntu 27.04 To Use ntpd-rs By Default
Canonical has reaffirmed its decision to make ntpd-rs the default time synchronization service in Ubuntu 27.04. The switch highlights the importance of precise timekeeping, which is critical for security features such as TLS certificate validation and Kerberos authentication. Inaccurate system clocks can lead to expired certificates and authentication failures, prompting the need for a reliable NTP implementation. Ubuntu 26.10 already includes ntpd-rs for testing, indicating the company's commitment to improving system security and reliability.
