ZonedDateTime now() Method in Java with Examples

Last Updated : 21 Jan, 2019

In ZonedDateTime class, there are three types of now() method depending upon the parameters passed to it.

method of a

class used to obtain the current date-time from the system clock in the default time-zone.This method will return ZonedDateTime based on system clock with default time-zone to obtain the current date-time. The zone and offset will be set based on the time-zone in the clock.

public static ZonedDateTime now()

This method accepts no parameter.

This method returns the current date-time using the system clock. Below programs illustrate the now() method:

// Java program to demonstrate
// ZonedDateTime.now() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // create an ZonedDateTime object
        ZonedDateTime lt
            = ZonedDateTime.now();

        // print result
        System.out.println("ZonedDateTime : "
                           + lt);
    }
}

ZonedDateTime : 2019-01-21T05:36:18.973Z[Etc/UTC]

method of a

class used to return the current date-time based on the specified clock passed as parameter.The zone and offset will be set based on the time-zone in the clock.

public static ZonedDateTime now(Clock clock)

This method accepts

as parameter which is the clock to use.

This method returns

. Below programs illustrate the now() method:

// Java program to demonstrate
// ZonedDateTime.now() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a clock
        Clock cl = Clock.systemUTC();

        // create an ZonedDateTime object using now(Clock)
        ZonedDateTime lt
            = ZonedDateTime.now(cl);

        // print result
        System.out.println("ZonedDateTime : "
                           + lt);
    }
}

ZonedDateTime : 2019-01-21T05:36:25.966Z

method of a

class used to return the current date-time from system clock in the specified time-zone passed as parameter.Specifying the time-zone avoids dependence on the default time-zone. The offset will be calculated from the specified time-zone.

public static ZonedDateTime now(ZoneId zone)

This method accepts

as parameter which is the zone to use.

This method returns

. Below programs illustrate the now() method:

// Java program to demonstrate
// ZonedDateTime.now() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a clock
        ZoneId zid = ZoneId.of("Europe/Paris");

        // create an ZonedDateTime object using now(zoneId)
        ZonedDateTime lt
            = ZonedDateTime.now(zid);

        // print result
        System.out.println("ZonedDateTime : "
                           + lt);
    }
}
