public static Clock systemDefaultZone()

The method is available since Java 8.

Parameters

Return value

Returns a clock that is using the best available system clock in the default time zone, never null.

Example usage

In the following code we use java.time.Clock.systemDefaultZone(): 

package com.farenda.java.time;

import java.time.Clock;
import java.time.ZoneId;

public class ClockExample {

    public static void main(String[] args) {
        Clock clock = Clock.systemDefaultZone();
        System.out.println("Clock's zone: " + clock.getZone());
        System.out.println("System.currentTimeMillis: "
                + System.currentTimeMillis());
        System.out.println("Clock's millis: " + clock.millis());

        // It's the same as:
        Clock sysClock = Clock.system(ZoneId.systemDefault());
        System.out.println("System clock's zone: "
                + sysClock.getZone());
    }
}

The above code produces the following output: 

Clock's zone: Europe/Warsaw
System.currentTimeMillis: 1464253352633
Clock's millis: 1464253352633
System clock's zone: Europe/Warsaw
