Struct NtpClient 

pub struct NtpClient {
    pub filter: ClockFilter,
    pub drift: DriftEstimator,
    pub poll_interval: u32,
    pub stratum: u8,
    pub step_applied: bool,
    pub start_ms: u64,
}

NTP client managing time synchronization with one or more servers.

Fields

filter: ClockFilter

Clock filter for selecting best sample

drift: DriftEstimator

Drift estimator for frequency compensation

poll_interval: u32

Current poll interval in seconds

stratum: u8

Our stratum level (one more than best server’s stratum)

step_applied: bool

Whether a step correction has been applied since boot

start_ms: u64

Measurement start time in ms (for drift tracking)

Implementations

impl NtpClient

pub fn new() -> Self

Create a new NTP client.

pub fn create_request(&self, transmit_ts: NtpTimestamp) -> [u8; 48]

Create a client request packet for the given transmit timestamp.

pub fn process_response( &mut self, response: &[u8], t1: &NtpTimestamp, t4: &NtpTimestamp, ) -> Option<NtpMeasurement>

Process a server response and return the computed measurement.

• response: the raw 48-byte NTP response
• t1: our original transmit timestamp
• t4: our receive timestamp (when we got the response)

pub fn adjust_clock(&mut self) -> i64

Decide whether to step (instant jump) or slew (gradual adjust) the clock, and apply the correction via the RTC integration point.

Returns the applied correction in milliseconds.

pub fn get_poll_interval(&self) -> u32

Get the current poll interval in seconds.

Trait Implementations

impl Default for NtpClient

fn default() -> Self

Returns the “default value” for a type.
