Struct TaiClock 

pub struct TaiClock;

Available on 64-bit and Linux and crate feature std and (Linux or macOS) only.

International Atomic Time, CLOCK_TAI, on Linux.

The wall clock plus the kernel’s TAI offset, which chrony or ptp4l sets to the leap seconds since 1972; until one does, the offset is zero and this reads the wall clock.

Examples

use t2t_clock::{Clock, SystemClock, TaiClock};
use t2t_core::Timedelta;

let ahead = Timedelta::from_nanos(TaiClock.now().as_nanos() - SystemClock.now().as_nanos());
assert!(ahead < Timedelta::from_secs(60), "at most the leap seconds since 1972: {ahead}");
