ZonedDateTime now() Method in Java with Examples

21 Jan, 2019
In ZonedDateTime class, there are three types of now() method depending upon the parameters passed to it.
now() method of a ZonedDateTime 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.
Syntax:
public static ZonedDateTime now()

Parameters: This method accepts no parameter.
Return value: This method returns the current date-time using the system clock.
Below programs illustrate the now() method:Program 1:
// 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]

now(Clock clock) method of a ZonedDateTime 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.
Syntax:
public static ZonedDateTime now(Clock clock)

Parameters: This method accepts clock as parameter which is the clock to use.
Return value: This method returns the current date-time.
Below programs illustrate the now() method:Program 1:
// 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

now(ZoneId zone) method of a ZonedDateTime 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.
Syntax:
public static ZonedDateTime now(ZoneId zone)

Parameters: This method accepts zone as parameter which is the zone to use.
Return value: This method returns the current date-time.
Below programs illustrate the now() method:Program 1:
// 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);    }}
