如何将毫秒转换为“hh:mm:ss”格式？

发布于 2024-12-29 15:00:47 字数 1316 浏览 6 评论 0原文

我很困惑。在偶然发现这个线程之后，我试图弄清楚如何格式化具有 hh:mm:ss 格式的倒计时器。

这是我的尝试 -

//hh:mm:ss
String.format("%02d:%02d:%02d", 
    TimeUnit.MILLISECONDS.toHours(millis),
    TimeUnit.MILLISECONDS.toMinutes(millis) - 
    TimeUnit.MINUTES.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
    TimeUnit.MILLISECONDS.toSeconds(millis) - 
    TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));

因此，当我尝试像 3600000ms 这样的值时，我得到 01:59:00，这是错误的，因为它应该是 01:00： 00。显然我的逻辑有问题，但目前我看不出问题是什么！

有人可以帮忙吗？

编辑-

修复它。以下是将毫秒格式化为 hh:mm:ss 格式的正确方法 -

//hh:mm:ss
String.format("%02d:%02d:%02d", 
    TimeUnit.MILLISECONDS.toHours(millis),
    TimeUnit.MILLISECONDS.toMinutes(millis) - 
    TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
    TimeUnit.MILLISECONDS.toSeconds(millis) - 
    TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis))));

问题在于 TimeUnit.MINUTES.toMinutes(TimeUnit.MILLISECONDS.toHours(millis))。它应该是这个 TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)) 。

原文

I'm confused. After stumbling upon this thread, I tried to figure out how to format a countdown timer that had the format hh:mm:ss.

Here's my attempt -

//hh:mm:ss
String.format("%02d:%02d:%02d", 
    TimeUnit.MILLISECONDS.toHours(millis),
    TimeUnit.MILLISECONDS.toMinutes(millis) - 
    TimeUnit.MINUTES.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
    TimeUnit.MILLISECONDS.toSeconds(millis) - 
    TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));

So, when I try a value like 3600000ms, I get 01:59:00, which is wrong since it should be 01:00:00. Obviously there's something wrong with my logic, but at the moment, I cannot see what it is!

Can anyone help?

Edit -

Fixed it. Here's the right way to format milliseconds to hh:mm:ss format -

//hh:mm:ss
String.format("%02d:%02d:%02d", 
    TimeUnit.MILLISECONDS.toHours(millis),
    TimeUnit.MILLISECONDS.toMinutes(millis) - 
    TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
    TimeUnit.MILLISECONDS.toSeconds(millis) - 
    TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis))));

The problem was this TimeUnit.MINUTES.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)). It should have been this TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)) instead.

要走干脆点 2025-01-05 15:00:47

您真的很接近：

String.format("%02d:%02d:%02d", 
TimeUnit.MILLISECONDS.toHours(millis),
TimeUnit.MILLISECONDS.toMinutes(millis) -  
TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)), // The change is in this line
TimeUnit.MILLISECONDS.toSeconds(millis) - 
TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));

您使用分钟而不是小时将小时转换为毫秒。

顺便说一句，我喜欢您使用 TimeUnit API :)

这是一些测试代码：

public static void main(String[] args) throws ParseException {
    long millis = 3600000;
    String hms = String.format("%02d:%02d:%02d", TimeUnit.MILLISECONDS.toHours(millis),
            TimeUnit.MILLISECONDS.toMinutes(millis) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
            TimeUnit.MILLISECONDS.toSeconds(millis) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));
    System.out.println(hms);
}

输出：

01:00:00

我意识到通过使用模数除法而不是减法可以大大简化上面的代码：

String hms = String.format("%02d:%02d:%02d", TimeUnit.MILLISECONDS.toHours(millis),
    TimeUnit.MILLISECONDS.toMinutes(millis) % TimeUnit.HOURS.toMinutes(1),
    TimeUnit.MILLISECONDS.toSeconds(millis) % TimeUnit.MINUTES.toSeconds(1));

仍然使用 TimeUnit API 适用于所有魔法值，并给出完全相同的输出。

You were really close:

String.format("%02d:%02d:%02d", 
TimeUnit.MILLISECONDS.toHours(millis),
TimeUnit.MILLISECONDS.toMinutes(millis) -  
TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)), // The change is in this line
TimeUnit.MILLISECONDS.toSeconds(millis) - 
TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));

You were converting hours to millisseconds using minutes instead of hours.

BTW, I like your use of the TimeUnit API :)

Here's some test code:

public static void main(String[] args) throws ParseException {
    long millis = 3600000;
    String hms = String.format("%02d:%02d:%02d", TimeUnit.MILLISECONDS.toHours(millis),
            TimeUnit.MILLISECONDS.toMinutes(millis) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
            TimeUnit.MILLISECONDS.toSeconds(millis) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));
    System.out.println(hms);
}

Output:

01:00:00

I realised that my code above can be greatly simplified by using a modulus division instead of subtraction:

String hms = String.format("%02d:%02d:%02d", TimeUnit.MILLISECONDS.toHours(millis),
    TimeUnit.MILLISECONDS.toMinutes(millis) % TimeUnit.HOURS.toMinutes(1),
    TimeUnit.MILLISECONDS.toSeconds(millis) % TimeUnit.MINUTES.toSeconds(1));

Still using the TimeUnit API for all magic values, and gives exactly the same output.

停顿的约定 2025-01-05 15:00:47

其通用方法相当简单：

public static String convertSecondsToHMmSs(long seconds) {
    long s = seconds % 60;
    long m = (seconds / 60) % 60;
    long h = (seconds / (60 * 60)) % 24;
    return String.format("%d:%02d:%02d", h,m,s);
}

The generic method for this is fairly simple:

public static String convertSecondsToHMmSs(long seconds) {
    long s = seconds % 60;
    long m = (seconds / 60) % 60;
    long h = (seconds / (60 * 60)) % 24;
    return String.format("%d:%02d:%02d", h,m,s);
}

// New date object from millis
Date date = new Date(millis);
// formattter 
SimpleDateFormat formatter= new SimpleDateFormat("HH:mm:ss.SSS");
formatter.setTimeZone(TimeZone.getTimeZone("UTC"));
// Pass date object
String formatted = formatter.format(date );

您还可以使用新的 DateTime API

     var formatted = DateTimeFormatter.ofPattern("HH:mm:ss.SSS")
            .withZone(ZoneId.of("UTC"))
            .format(Instant.ofEpochMilli(millis));

这对我有用，与 kotlin 一起

fun formatToDigitalClock(miliSeconds: Long): String {
        val hours = TimeUnit.MILLISECONDS.toHours(miliSeconds).toInt() % 24
        val minutes = TimeUnit.MILLISECONDS.toMinutes(miliSeconds).toInt() % 60
        val seconds = TimeUnit.MILLISECONDS.toSeconds(miliSeconds).toInt() % 60
        return when {
            hours > 0 -> String.format("%d:%02d:%02d", hours, minutes, seconds)
            minutes > 0 -> String.format("%02d:%02d", minutes, seconds)
            seconds > 0 -> String.format("00:%02d", seconds)
            else -> {
                "00:00"
            }
        }
    }

this worked for me, with kotlin

fun formatToDigitalClock(miliSeconds: Long): String {
        val hours = TimeUnit.MILLISECONDS.toHours(miliSeconds).toInt() % 24
        val minutes = TimeUnit.MILLISECONDS.toMinutes(miliSeconds).toInt() % 60
        val seconds = TimeUnit.MILLISECONDS.toSeconds(miliSeconds).toInt() % 60
        return when {
            hours > 0 -> String.format("%d:%02d:%02d", hours, minutes, seconds)
            minutes > 0 -> String.format("%02d:%02d", minutes, seconds)

Java 9

    Duration timeLeft = Duration.ofMillis(3600000);
    String hhmmss = String.format("%02d:%02d:%02d", 
            timeLeft.toHours(), timeLeft.toMinutesPart(), timeLeft.toSecondsPart());
    System.out.println(hhmmss);

打印：

01:00:00

你让库方法为你完成涉及的转换是正确的。 java.time，现代 Java 日期和时间 API，或者更准确地说，它的 Duration 类比 TimeUnit 更优雅、更不易出错。 。

我使用的toMinutesPart和toSecondsPart方法是在Java 9中引入的。Java

6、7和8的

    long hours = timeLeft.toHours();
    timeLeft = timeLeft.minusHours(hours);
    long minutes = timeLeft.toMinutes();
    timeLeft = timeLeft.minusMinutes(minutes);
    long seconds = timeLeft.toSeconds();
    String hhmmss = String.format("%02d:%02d:%02d", hours, minutes, seconds);
    System.out.println(hhmmss);

输出与上面相同。

问题：这在 Java 6 和 7 中如何工作？

  • 在 Java 8 及更高版本以及较新的 Android 设备（据我所知，从 API 级别 26 开始）中，java.time 是内置的。
  • 在 Java 6 和 7 中，获取 ThreeTen Backport，即现代类的向后移植（ThreeTen for JSR 310；请参阅底部的链接）。
  • 在（较旧的）Android 上使用 ThreeTen Backport 的 Android 版本。它被称为 ThreeTenABP。并确保使用子包从 org. Threeten.bp 导入日期和时间类。

Java 9

    Duration timeLeft = Duration.ofMillis(3600000);
    String hhmmss = String.format("%02d:%02d:%02d", 
            timeLeft.toHours(), timeLeft.toMinutesPart(), timeLeft.toSecondsPart());
    System.out.println(hhmmss);

This prints:

01:00:00

You are doing right in letting library methods do the conversions involved for you. java.time, the modern Java date and time API, or more precisely, its Duration class does it more elegantly and in a less error-prone way than TimeUnit.

The toMinutesPart and toSecondsPart methods I used were introduced in Java 9.

Java 6, 7 and 8

    long hours = timeLeft.toHours();
    timeLeft = timeLeft.minusHours(hours);
    long minutes = timeLeft.toMinutes();
    timeLeft = timeLeft.minusMinutes(minutes);
    long seconds = timeLeft.toSeconds();
    String hhmmss = String.format("%02d:%02d:%02d", hours, minutes, seconds);
    System.out.println(hhmmss);

The output is the same as above.

Question: How can that work in Java 6 and 7?

  • In Java 8 and later and on newer Android devices (from API level 26, I’m told) java.time comes built-in.
  • In Java 6 and 7 get the ThreeTen Backport, the backport of the modern classes (ThreeTen for JSR 310; see the links at the bottom).
  • On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from org.threeten.bp with subpackages.

标记为正确的答案有一个小错误，

String myTime = String.format("%02d:%02d:%02d",
            TimeUnit.MILLISECONDS.toHours(millis),
            TimeUnit.MILLISECONDS.toMinutes(millis) -
                    TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)), // The change is in this line
            TimeUnit.MILLISECONDS.toSeconds(millis) -
                    TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));

例如，这是我得到的值的示例：

417474:44:19

这是获得正确格式的解决方案是：

String myTime =  String.format("%02d:%02d:%02d",
                //Hours
                TimeUnit.MILLISECONDS.toHours(millis) -
                        TimeUnit.DAYS.toHours(TimeUnit.MILLISECONDS.toDays(millis)),
                //Minutes
                TimeUnit.MILLISECONDS.toMinutes(millis) -
                        TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
                //Seconds
                TimeUnit.MILLISECONDS.toSeconds(millis) -
                        TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));

获得正确的格式：

18:44:19

获得格式的其他选项 hh:mm:ss 只是：

   Date myDate = new Date(timeinMillis);
   SimpleDateFormat formatter = new SimpleDateFormat("HH:mm:ss");
   String myTime = formatter.format(myDate);

The answer marked as correct has a little mistake,

String myTime = String.format("%02d:%02d:%02d",
            TimeUnit.MILLISECONDS.toHours(millis),
            TimeUnit.MILLISECONDS.toMinutes(millis) -
                    TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)), // The change is in this line
            TimeUnit.MILLISECONDS.toSeconds(millis) -
                    TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));

for example this is an example of the value that i get:

417474:44:19

This is the solution to get the right format is:

String myTime =  String.format("%02d:%02d:%02d",
                //Hours
                TimeUnit.MILLISECONDS.toHours(millis) -
                        TimeUnit.DAYS.toHours(TimeUnit.MILLISECONDS.toDays(millis)),
                //Minutes
                TimeUnit.MILLISECONDS.toMinutes(millis) -
                        TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
                //Seconds
                TimeUnit.MILLISECONDS.toSeconds(millis) -
                        TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));

getting as a result a correct format:

18:44:19

other option to get the format hh:mm:ss is just :

   Date myDate = new Date(timeinMillis);
   SimpleDateFormat formatter = new SimpleDateFormat("HH:mm:ss");
   String myTime = formatter.format(myDate);

根据 Bohemian 的答案，我们不需要使用 TimeUnit 来查找已知值。
更优化的代码将是

String hms = String.format("%02d:%02d:%02d", millisLeft/(3600*1000),
                    millisLeft/(60*1000) % 60,
                    millisLeft/1000 % 60);

希望它有帮助

Going by Bohemian's answer we need need not use TimeUnit to find a known value.
Much more optimal code would be

String hms = String.format("%02d:%02d:%02d", millisLeft/(3600*1000),
                    millisLeft/(60*1000) % 60,
                    millisLeft/1000 % 60);

下面的代码以两种方式将

23:59:58:999 转换为 86398999

以及将

86398999 转换为 23:59:58:999

import java.util.concurrent.TimeUnit;

public class TimeUtility {

    public static void main(String[] args) {

        long currentDateTime = System.currentTimeMillis();

        String strTest = "23:59:58:999";

        System.out.println(l);
        l += 1;

        String sec = strTime.substring(6, 8);
        String milli = strTime.substring(9, 12);
        int h = Integer.parseInt(hour);
        int m = Integer.parseInt(min);
        int s = Integer.parseInt(sec);
        int ms = Integer.parseInt(milli);

        String strDebug = String.format("%02d:%02d:%02d:%03d", h, m, s, ms);
        //System.out.println(strDebug);
        long lH = h * 60 * 60 * 1000;

        long lS = s * 1000;

        retVal = lH + lM + lS + ms;
        return retVal;
    }

    /**

    private static String milliToString(long millis) {

        long hrs = TimeUnit.MILLISECONDS.toHours(millis) % 24;
        long min = TimeUnit.MILLISECONDS.toMinutes(millis) % 60;
        long sec = TimeUnit.MILLISECONDS.toSeconds(millis) % 60;

        //System.out.println(toRet);
        return toRet;
    }
}

The code below does the conversion in both way

23:59:58:999 to 86398999

and than

86398999 to 23:59:58:999

我按照第一个答案中所示进行了尝试。它有效，但负号让我陷入困惑。 Groovy 我的回答：

import static java.util.concurrent.TimeUnit.*

...

private static String formatElapsedTime(long millis) {

    int hrs = MILLISECONDS.toHours(millis) % 24
    int min = MILLISECONDS.toMinutes(millis) % 60
    int sec = MILLISECONDS.toSeconds(millis) % 60
    int mls = millis % 1000

    sprintf( '%02d:%02d:%02d (%03d)', [hrs, min, sec, mls])
}

I tried as shown in the first answer. It works, but minus brought me into confusion. My answer by Groovy:

import static java.util.concurrent.TimeUnit.*

...

private static String formatElapsedTime(long millis) {

    int hrs = MILLISECONDS.toHours(millis) % 24
    int min = MILLISECONDS.toMinutes(millis) % 60
    int sec = MILLISECONDS.toSeconds(millis) % 60
    int mls = millis % 1000

    sprintf( '%02d:%02d:%02d (%03d)', [hrs, min, sec, mls])

val minutes = String.format("%02d",
                        TimeUnit.MILLISECONDS.toMinutes(milSecs) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(milSecs)))

                        TimeUnit.MILLISECONDS.toSeconds(milSecs) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(milSecs)))

，其中 milSecs 是毫秒

For Kotlin

val hours = String.format("%02d", TimeUnit.MILLISECONDS.toHours(milSecs))
val minutes = String.format("%02d",
                        TimeUnit.MILLISECONDS.toMinutes(milSecs) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(milSecs)))

好吧，你可以尝试这样的事情：

public String getElapsedTimeHoursMinutesSecondsString() {       
     long elapsedTime = getElapsedTime();  
     String format = String.format("%%0%dd", 2);  
     elapsedTime = elapsedTime / 1000;  
     String seconds = String.format(format, elapsedTime % 60);  
     String minutes = String.format(format, (elapsedTime % 3600) / 60);  
     String hours = String.format(format, elapsedTime / 3600);  
     String time =  hours + ":" + minutes + ":" + seconds;  
     return time;  
 }

将毫秒转换为时间值

Well, you could try something like this, :

public String getElapsedTimeHoursMinutesSecondsString() {       
     long elapsedTime = getElapsedTime();  
     String format = String.format("%%0%dd", 2);  
     elapsedTime = elapsedTime / 1000;  
     String seconds = String.format(format, elapsedTime % 60);  
     String minutes = String.format(format, (elapsedTime % 3600) / 60);  
     String hours = String.format(format, elapsedTime / 3600);  
     String time =  hours + ":" + minutes + ":" + seconds;  
     return time;  
 }

public String millisToHhMmSs(long milliseconds) {
    Duration duration = Duration.ofMillis(milliseconds);
    long hours = duration.toHoursPart();
    long minutes = duration.toMinutesPart();
    long seconds = duration.toSecondsPart();
    return String.format("%02d:%02d:%02d", hours, minutes, seconds);

Using Java 9 new Duration methods (toPart)

public String millisToHhMmSs(long milliseconds) {
    Duration duration = Duration.ofMillis(milliseconds);
    long hours = duration.toHoursPart();
    long minutes = duration.toMinutesPart();
    long seconds = duration.toSecondsPart();
