NTP

Enable NTP when the core needs a clock offset for protocols. Default settings are usually sufficient.

ntp:
  enable: true
  server: time.apple.com
  port: 123
  interval: 30
  write-to-system: false
  dialer-proxy: DIRECT

Field	How to configure it
enable	Enable time synchronization
server / port	NTP server and UDP port; this example uses time.apple.com:123
interval	Synchronization interval in minutes, 30 here
dialer-proxy	Outbound for requests; another node must support UDP
write-to-system	Always disabled on Apple platforms; device time is unchanged

If synchronization fails, check UDP connectivity and the selected outbound.

Platform behavior and field status

NTP supplies a clock offset to protocols without changing device time.

6 fields shown

Field	Type	iOS	macOS	tvOS	Platform notes
ntp.dialer-proxy	String	Managed / limited	Managed / limited	Managed / limited	Configures time synchronization for protocol time offsets; does not change the device clock.
ntp.enable	Boolean	Managed / limited	Managed / limited	Managed / limited	Configures time synchronization for protocol time offsets; does not change the device clock.
ntp.interval	Integer	Managed / limited	Managed / limited	Managed / limited	Time synchronization interval in minutes.
ntp.port	Integer	Managed / limited	Managed / limited	Managed / limited	Configures time synchronization for protocol time offsets; does not change the device clock.
ntp.server	String	Managed / limited	Managed / limited	Managed / limited	Configures time synchronization for protocol time offsets; does not change the device clock.
ntp.write-to-system	Boolean	Unsupported	Unsupported	Unsupported	Always false; does not change the device clock.
