An incorrect time will be displayed on a system configured to use one of the affected time zones if the /usr/share/zoneinfo and /etc/localtime files are not updated, and all applications on the system that rely on the system time, such as cron(8) and syslog(8), will be affected. With the default configuration, FreeBSD systems cannot file updates to the installed leap-seconds.list file. Since no leap second was introduced at the end of 2023, the leap-seconds.list file included with all supported FreeBSD releases is still accurate. Moreover, ntpd(8) is able to receive updated leap second information from its peers. However, a diagnostic warning about an expired leap-seconds.list is printed at startup.
