Java Clock tickMinutes() method in Java with Examples

java.time.Clock.tickMinutes(ZoneId zone) method is a static method of Clock class that returns the current instant ticking in whole minutes using the best available system clock and the time-zone of that instant is same as the time-zone passed as a parameter.

Nanosecond and second fields of the clock are set to zero to round the instant in the whole minute. The underlying clock is the best system clock which is the same as the system (ZoneId). A duration of zero or one nanosecond would have no effect on the base clock method. These will return the same base clock.

The returned clock is also immutable, thread-safe, and Serializable and this method is equivalent to tick(system(zone), Duration.ofMinutes(1)).

Syntax:

public static Clock tickMinutes(ZoneId zone)

Parameters: This method takes a mandatory parameter zone, which is the time-zone used to round off instant of a clock in the whole minute.

Return Value: This method returns a clock that returns the current instant ticking in whole minutes
with zone same as zone passed as parameter.

Example:

Code:
ZoneId zoneId = ZoneId.of("Asia/Calcutta");
Clock clock = Clock.tickMinutes(zoneId);
System.out.println(clock.instant());

Output:
2018-08-21T19:55:00Z

Explanation::
method tickMinutes() returns the instant 
which ticks in a whole minute. It means the second
and nanosecond fields are zero, which can be 
visualized as the second field is empty in output.

Below programs illustrates tickMinutes() method of java.time.Clock class:

Program 1: When Clock is created with Zone “Asia/Calcutta” for printing instant of clock ticking in whole minute.

// Java program to demonstrate
// tickMinutes() method of Clock class

import java.time.*;

// create class
public class GFG {

    // Main method
    public static void main(String[] args)
    {
        // Zone Id with Zone Asia/Calcutta
        ZoneId zoneId = ZoneId.of("Asia/Calcutta");

        // create a clock which ticks in whole minute
        Clock clock = Clock.tickMinutes(zoneId);

        // print instance of clock
        System.out.println(clock.instant());
    }
}

Output:

2018-08-24T07:51:00Z

Program 2: Print the date and Time of clock with zone “Europe/Paris” and clock ticks per whole minute.

// Java program to demonstrate
// tickMinutes() method of Clock class

import java.time.*;

// create class
public class tickMinutesMethodDemo {

    // Main method
    public static void main(String[] args)
    {

        // Zone Id with Zone Europe/Paris
        ZoneId zoneId = ZoneId.of("Europe/Paris");

        // create a clock which ticks in whole minute
        Clock clock = Clock.tickMinutes(zoneId);

        // get ZonedDateTime object to print time
        ZonedDateTime time = clock.instant()
                                 .atZone(clock.getZone());

        // print time variable value
        System.out.println("Date and Time :" + time);
    }
}

Output:

Date and Time :2018-08-24T09:52+02:00[Europe/Paris]
