Struct SystemClock 

pub struct SystemClock;

The wall clock, CLOCK_REALTIME.

The clock whose readings mean something off this machine, which makes it the stamp for a capture. A time service disciplines it, so it may step backwards across a correction; a span that must never run backwards is measured on MonotonicClock or a Counter.

Examples

use t2t_clock::{Clock, SystemClock};
use t2t_core::Timestamp;

assert!(SystemClock.now() > Timestamp::from_secs(1_700_000_000), "past November 2023");
