Struct zenoh_protocol_core::NTP64

pub struct NTP64(pub u64);

A NTP 64-bits format as specified in RFC-5909

The first 32-bits part is the number of second since the EPOCH of the physical clock, and the second 32-bits part is the fraction of second.
In case it’s part of a crate::Timestamp generated by an crate::HLC the last few bits are replaced by the HLC logical counter. The size of this counter currently hard-coded in crate::CSIZE.

Note that this timestamp in actually similar to a std::time::Duration, as it doesn’t define an EPOCH. Only the NTP64::to_system_time() and std::fmt::Display::fmt() operations assume that it’s relative to UNIX_EPOCH (1st Jan 1970) to display the timpestamp in RFC-3339 format.

pub fn as_secs(&self) -> u32

Returns the 32-bits seconds part.

pub fn subsec_nanos(&self) -> u32

Returns the 32-bits fraction of second part converted to nanoseconds.

pub fn to_duration(self) -> Duration
