Clock Class offset()方法 (Clock Class offset() method)

• offset() method is available in java.time package.

  offset()方法在java.time包中可用。

• offset() method is used to generate a new Clock from the given base clock with added the given Duration.

  offset()方法用于根據(jù)給定的基本時鐘加上給定的Duration來生成新Clock。

• offset() method is a static method, it is accessible with the class name and if we try to access the method with the class object then we will not get an error.

  offset()方法是一個靜態(tài)方法，可以使用類名進行訪問，如果嘗試使用類對象訪問該方法，則不會出錯。

• offset() method does not throw an exception at the time of representing Clock.

  offset()方法在表示Clock時不會引發(fā)異常。

Syntax:

句法：

public static Clock offset(Clock base_cl, Duration off);

Parameter(s):

參數(shù)：

• Clock base_cl – represents the base clock in which to add the given duration.

  Clock base_cl –表示要添加給定持續(xù)時間的基本時鐘。

• Duration off – represents the offset to add to the given base clock (base_cl).

  持續(xù)時間關(guān)閉 –表示要添加到給定基本時鐘(base_cl)的偏移量。

Return value:

返回值：

The return type of this method is Clock, it returns the Clock object that is available with added the given offset.

此方法的返回類型為Clock ，它返回添加了給定偏移量后可用的Clock對象。

Example:

例：

// Java program to demonstrate the example // of offset(Clock base_cl, Duration off) method of Clockimport java.time.*;public class OffsetOfClock {public static void main(String args[]) {// Instantiates two ZoneId for Accra and AsmaraZoneId zone_1 = ZoneId.of("Africa/Accra");ZoneId zone_2 = ZoneId.of("Africa/Asmara");// Initialize two Clock objects // and one DurationClock cl1 = Clock.system(zone_1);Clock cl2 = Clock.system(zone_2);Duration offset = Duration.ofMinutes(20);// generates a new Clock from the// given clock(cl1) with the given duration addedClock cl_offset = cl1.offset(cl1, offset);// Display cl1 and cl_offset instantSystem.out.println("cl1.instant(): " + cl1.instant());System.out.println("cl_offset.instant(): " + cl_offset.instant());System.out.println();// generates a new Clock from the// given clock(cl2) with the given duration addedcl_offset = cl2.offset(cl2, offset);// Display cl2 and cl_offset instantSystem.out.println("cl2.instant(): " + cl2.instant());System.out.println("cl_offset.instant(): " + cl_offset.instant());} }

Output

輸出量

cl1.instant(): 2020-05-13T19:04:36.242559Z cl_offset.instant(): 2020-05-13T19:24:36.322896Zcl2.instant(): 2020-05-13T19:04:36.324623Z cl_offset.instant(): 2020-05-13T19:24:36.327267Z
