如何在 Java 中將紀元時間轉換為 MySQL 時間戳記？

import java.time.LocalDateTime;

// Convert epoch time in milliseconds to seconds
long epochSeconds = System.currentTimeMillis() / 1000;

// Create a LocalDateTime object from the epoch seconds
LocalDateTime timestamp = LocalDateTime.ofEpochSecond(epochSeconds, 0, java.time.ZoneOffset.UTC);

// Format the LocalDateTime object as a MySQL timestamp string
String mySQLTimestamp = timestamp.toString();

import java.text.SimpleDateFormat;
import java.util.Date;

// Convert epoch time in milliseconds to a Date object
Date date = new Date(epochSeconds * 1000);

// Create a SimpleDateFormat to format the Date as a MySQL timestamp string
SimpleDateFormat sdf = new SimpleDateFormat("YYYY-MM-DD HH:MM:SS");

// Format the Date object as a MySQL timestamp string
String mySQLTimestamp = sdf.format(date);
