ChronoZonedDateTime接口的toEpochSecond()方法用於將此ChronoZonedDateTime轉換為自1970-01-01T00:00:00Z以來的秒數。該方法將此ChronoZonedDateTime與作為參數傳遞的偏移量相結合,以計算epoch-second值,該值是從1970-01-01T00:00:00Z開始經過的秒數。時期之後的時間軸上的瞬間為正,早期為負。
用法:
default long toEpochSecond()
參數:此方法不接受任何參數。
返回值:此方法返回long,它是自1970-01-01T00:00:00Z的紀元以來的秒數,可能為負數。
以下示例程序旨在說明toEpochSecond()方法:
示例1:
// Java program to demonstrate
// ChronoZonedDateTime.toEpochSecond() method
import java.time.*;
import java.time.chrono.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] args)
{
// create ChronoZonedDateTime object
ChronoZonedDateTime time
= ZonedDateTime
.parse(
"2018-12-06T19:21:12.123+05:30[Asia/Calcutta]");
// print ChronoZonedDateTime
System.out.println("ChronoZonedDateTime: "
+ time);
// print result
System.out.println("Epoch Second: "
+ time.toEpochSecond());
}
}
輸出:
ChronoZonedDateTime: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta] Epoch Second: 1544104272
示例2:
// Java program to demonstrate
// ChronoZonedDateTime.toEpochSecond() method
import java.time.*;
import java.time.chrono.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] args)
{
// create ChronoZonedDateTime object
ChronoZonedDateTime time
= ZonedDateTime.parse(
"1918-10-25T23:12:38.543+02:00[Europe/Paris]");
// print ChronoZonedDateTime
System.out.println("ChronoZonedDateTime: "
+ time);
// print result
System.out.println("Epoch Second: "
+ time.toEpochSecond());
}
}
輸出:
ChronoZonedDateTime: 1918-10-25T23:12:38.543Z[Europe/Paris] Epoch Second: -1615250842
