SNTP request result representation

Fields

seconds: u32

NTP server seconds value

seconds_fraction: u32

NTP server seconds fraction value

roundtrip: u64

Request roundtrip time in microseconds

offset: i64

Estimated difference between the NTP reference and the system time in microseconds

stratum: u8

Clock stratum of NTP server

precision: i8

Precision of NTP server as log2(seconds) - this should usually be negative

Implementations

impl NtpResult

pub fn new( seconds: u32, seconds_fraction: u32, roundtrip: u64, offset: i64, stratum: u8, precision: i8 ) -> Self

Create new NTP result Args:

• seconds - number of seconds
• seconds_fraction - number of seconds fraction
• roundtrip - calculated roundtrip in microseconds
• offset - calculated system clock offset in microseconds
• stratum - integer indicating the stratum (level of server’s hierarchy to stratum 0 - “reference clock”)
• precision - an exponent of two, where the resulting value is the precision of the system clock in seconds

pub fn sec(&self) -> u32

Returns number of seconds reported by an NTP server

pub fn sec_fraction(&self) -> u32

Returns number of seconds fraction reported by an NTP server

pub fn roundtrip(&self) -> u64

Returns request’s roundtrip time (client -> server -> client) in microseconds

pub fn offset(&self) -> i64

Returns system clock offset value in microseconds

pub fn stratum(&self) -> u8

Returns reported stratum value (level of server’s hierarchy to stratum 0 - “reference clock”)

pub fn precision(&self) -> i8

Returns reported precision value (an exponent of two, which results in the precision of server’s system clock in seconds)
