时间差获取和计算

获取时差值(时、分、秒)

• 将时差值转换为需要的差数。

import java.util.concurrent.TimeUnit;

String offlineDay = "2";
System.out.println("天-->小时:" + TimeUnit.DAYS.toHours(Long.parseLong(offlineDay)));
System.out.println("天-->分钟:" + TimeUnit.DAYS.toMinutes(Long.parseLong(offlineDay)));
System.out.println("天-->秒:" + TimeUnit.DAYS.toSeconds(Long.parseLong(offlineDay)));

String offlineSecond = "172800";
System.out.println("秒-->小时:" + TimeUnit.SECONDS.toDays(Long.parseLong(offlineSecond)));
System.out.println("秒-->分钟:" + TimeUnit.SECONDS.toHours(Long.parseLong(offlineSecond)));
System.out.println("秒-->秒:" + TimeUnit.SECONDS.toMinutes(Long.parseLong(offlineSecond)));

结果：

转换时差值为天数

• 将时差转换为需要的天数

// 假设为时间差，单位为毫秒
long timeDifference = 2880 * 60 * 1000 + 2 * 60 * 60 * 1000 + 3 * 60 * 1000 + 5 * 1000;
long seconds = timeDifference / 1000;
long minutes = seconds / 60;
long hours = minutes / 60;
long days = hours / 24;
String timeString = String.format("%d天 %d小时 %d分钟 %d秒", days, hours % 24, minutes % 60, seconds % 60);
System.out.println(timeString);

结果：
