This configuration file controls NTP network time synchronization. NTP= A space separated list of NTP servers host names or IP addresses. During runtime this list is combined with any per-interface NTP servers acquired from systemd-networkd.service8. systemd-timesyncd will contact all configured system or per-interface servers in turn until one is found that responds. This setting defaults to the empty list. FallbackNTP= A space separated list of NTP server host names or IP addresses to be used as the fallback NTP servers. Any per-interface NTP servers obtained from systemd-networkd.service8 take precedence over this setting, as do any servers set via NTP= above. This setting is hence only used if no other NTP server information is known. If this option is not given, a compiled-in list of NTP servers is used instead. systemd1, systemd-timesyncd.service8, systemd-networkd.service8
