현재 시각 조회, 시간 차 계산, 슬립 기능을 제공합니다.

import​

import("std::time::clock");
import("std::time::diff");
import("std::time::sleep");
import("std::sys::time");

1. 구간 측정​

fun main() {
    var start: TimeSpec;
    var end: TimeSpec;

    time_now_monotonic(&start);
    time_sleep_ms(10);
    time_now_monotonic(&end);

    var elapsed_ns: i64 = time_diff_ns(start, end);
    var elapsed_ms: i64 = time_diff_ms(start, end);
}

2. 나노초 타임스탬프​

fun main() {
    var rt: i64 = time_now_realtime_ns();
    var mono: i64 = time_now_monotonic_ns();
}

3. sleep​

fun main() {
    time_sleep_us(500);
    time_sleep_ms(1);
    time_sleep_ns(100000);
}
