# os_clock

Access various operating system clocks (such as per-thread CPU Time, system clock, monotomic, etc) on Unix-family systems.

```rust

use os_clock::{self, Clock};

let clock = cpu_clock_for_current_thread();

clock.get_time();

```

Notably, a clock for the CPU time of one thread can be accessed from another thread:

```rust

let clock = cpu_clock_for_current_thread().unwrap();

loop {

    if clock.get_time().unwrap() > Duration::from_millis(5) {

        break;

    }

}

std::thread::spawn(move || {

    assert!(clock.get_time().unwrap() > Duration::from_millis(5));

    let self_clock = cpu_clock_for_current_thread().unwrap();

    assert!(self_clock.get_time().unwrap() < Duration::from_millis(1));

})

.join()

.unwrap();

```

## Compatibility

Works on recent iOS, Mac, as well as Unix-family systems with a `pthread.h` that defines `pthread_getcpuclockid` (most modern Linux).
