基于@siddhadev的回答，我写了一个将毫秒转换为格式化字符串的函数:

   /**
     * Convert a millisecond duration to a string format
     * 
     * @param millis A duration to convert to a string form
     * @return A string of the form "X Days Y Hours Z Minutes A Seconds".
     */
    public static String getDurationBreakdown(long millis) {
        if(millis < 0) {
            throw new IllegalArgumentException("Duration must be greater than zero!");
        }

        long days = TimeUnit.MILLISECONDS.toDays(millis);
        millis -= TimeUnit.DAYS.toMillis(days);
        long hours = TimeUnit.MILLISECONDS.toHours(millis);
        millis -= TimeUnit.HOURS.toMillis(hours);
        long minutes = TimeUnit.MILLISECONDS.toMinutes(millis);
        millis -= TimeUnit.MINUTES.toMillis(minutes);
        long seconds = TimeUnit.MILLISECONDS.toSeconds(millis);

        StringBuilder sb = new StringBuilder(64);
        sb.append(days);
        sb.append(" Days ");
        sb.append(hours);
        sb.append(" Hours ");
        sb.append(minutes);
        sb.append(" Minutes ");
        sb.append(seconds);
        sb.append(" Seconds");

        return(sb.toString());
    }

如果你知道时间差将小于一个小时，那么你可以使用以下代码:

    Calendar c1 = Calendar.getInstance();
    Calendar c2 = Calendar.getInstance();

    c2.add(Calendar.MINUTE, 51);

    long diff = c2.getTimeInMillis() - c1.getTimeInMillis();

    c2.set(Calendar.MINUTE, 0);
    c2.set(Calendar.HOUR, 0);
    c2.set(Calendar.SECOND, 0);

    DateFormat df = new SimpleDateFormat("mm:ss");
    long diff1 = c2.getTimeInMillis() + diff;
    System.out.println(df.format(new Date(diff1)));

结果是:51:00

我不会为此引入额外的依赖项(毕竟，除法并不那么难)，但如果您无论如何都在使用Commons Lang，还有DurationFormatUtils。

用法示例(从这里改编):

import org.apache.commons.lang3.time.DurationFormatUtils

public String getAge(long value) {
    long currentTime = System.currentTimeMillis();
    long age = currentTime - value;
    String ageString = DurationFormatUtils.formatDuration(age, "d") + "d";
    if ("0d".equals(ageString)) {
        ageString = DurationFormatUtils.formatDuration(age, "H") + "h";
        if ("0h".equals(ageString)) {
            ageString = DurationFormatUtils.formatDuration(age, "m") + "m";
            if ("0m".equals(ageString)) {
                ageString = DurationFormatUtils.formatDuration(age, "s") + "s";
                if ("0s".equals(ageString)) {
                    ageString = age + "ms";
                }
            }
        }
    }
    return ageString;
}   

例子:

long lastTime = System.currentTimeMillis() - 2000;
System.out.println("Elapsed time: " + getAge(lastTime)); 

//Output: 2s

注意:从两个LocalDateTime对象中获取millis可以使用:

long age = ChronoUnit.MILLIS.between(initTime, LocalDateTime.now())

首先，System.currentTimeMillis()和Instant.now()对于计时来说并不理想。它们都报告了挂钟时间，而计算机并不能准确地知道这个时间，而且它可能会不规律地移动，例如，如果NTP守护进程更正了系统时间，就会往回走。如果计时发生在一台机器上，那么应该使用System.nanoTime()。

其次，从Java 8开始，Java .time. duration是表示持续时间的最佳方式:

long start = System.nanoTime();
// do things...
long end = System.nanoTime();
Duration duration = Duration.ofNanos(end - start);
System.out.println(duration); // Prints "PT18M19.511627776S"
System.out.printf("%d Hours %d Minutes %d Seconds%n",
        duration.toHours(), duration.toMinutes() % 60, duration.getSeconds() % 60);
// prints "0 Hours 18 Minutes 19 Seconds"

这个主题已经被很好地覆盖了，我只是想分享我的函数，也许你可以使用这些函数，而不是导入整个库。

    public long getSeconds(ms) {
        return (ms/1000%60);
    }
    public long getMinutes(ms) {
        return (ms/(1000*60)%60);
    }
    public long getHours(ms) {
        return ((ms/(1000*60*60))%24);
    }

使用java。Java 8中的时间包:

Instant start = Instant.now();
Thread.sleep(63553);
Instant end = Instant.now();
System.out.println(Duration.between(start, end));

输出为ISO 8601 Duration格式:pt1m3.53s(1分3.553秒)。
