## Description

These configuration files control NTP network time synchronization.

## Options

The following settings are configured in the `[Time]` section:

`NTP=`

  A space-separated list of NTP server host names or IP addresses. During runtime this list is combined with any per-interface NTP servers acquired from systemd-networkd.service 8. systemd-timesyncd will contact all configured system or per-interface servers in turn until one is found that responds. This setting defaults to an 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.service 8 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.
