Create new Instant object from the System Clock

In Java we can use the Instant.now() static method to instantiate a new Instant object from the system clock as the example Java code below.

InstantNowExample1.java 

import java.time.Instant;

public class InstantNowExample1 {
    public static void main(String... args) {
        Instant instant = Instant.now();

        System.out.println(instant);
    }
}
The output as below.

Create new Instant object from the Specified Clock

In Java we can use the Instant.now(Clock clock) static method to instantiate a new Instant object from the specified clock as the example Java code below.

InstantNowExample2.java 

import java.time.Clock;
import java.time.Instant;

public class InstantNowExample2 {
    public static void main(String... args) {
        Clock utcClock = Clock.systemUTC();
        Clock systemClock = Clock.systemDefaultZone();

        Instant instant1 = Instant.now(utcClock);
        Instant instant2 = Instant.now(systemClock);

        System.out.println(instant1);
        System.out.println(instant2);
    }
}
The output as below.
