使用java。Java 8+内置的时间框架:

ZonedDateTime now = ZonedDateTime.now();
ZonedDateTime oldDate = now.minusDays(1).minusMinutes(10);
Duration duration = Duration.between(oldDate, now);
System.out.println("ISO-8601: " + duration);
System.out.println("Minutes: " + duration.toMinutes());

输出:

ISO-8601: PT24H10M 分钟:罢工,

有关更多信息，请参阅Oracle教程和ISO 8601标准。

让我来看看Joda Interval和Days之间的差异:

DateTime start = new DateTime(2012, 2, 6, 10, 44, 51, 0);
DateTime end = new DateTime(2012, 2, 6, 11, 39, 47, 1);
Interval interval = new Interval(start, end);
Period period = interval.toPeriod();
System.out.println(period.getYears() + " years, " + period.getMonths() + " months, " + period.getWeeks() + " weeks, " + period.getDays() + " days");
System.out.println(period.getHours() + " hours, " + period.getMinutes() + " minutes, " + period.getSeconds() + " seconds ");
//Result is:
//0 years, 0 months, *1 weeks, 1 days*
//0 hours, 54 minutes, 56 seconds 

//Period can set PeriodType,such as PeriodType.yearMonthDay(),PeriodType.yearDayTime()...
Period p = new Period(start, end, PeriodType.yearMonthDayTime());
System.out.println(p.getYears() + " years, " + p.getMonths() + " months, " + p.getWeeks() + " weeks, " + p.getDays() + "days");
System.out.println(p.getHours() + " hours, " + p.getMinutes() + " minutes, " + p.getSeconds() + " seconds ");
//Result is:
//0 years, 0 months, *0 weeks, 8 days*
//0 hours, 54 minutes, 56 seconds 

一个稍微简单一点的选择:

System.currentTimeMillis() - oldDate.getTime()

至于“更好”，你到底需要什么?将时间持续时间表示为小时数和天数等的问题是，由于日期的复杂性，它可能导致不准确和错误的期望(例如，由于夏令时，一天可能有23或25小时)。

public static String getDifferenceBtwTime(Date dateTime) {

    long timeDifferenceMilliseconds = new Date().getTime() - dateTime.getTime();
    long diffSeconds = timeDifferenceMilliseconds / 1000;
    long diffMinutes = timeDifferenceMilliseconds / (60 * 1000);
    long diffHours = timeDifferenceMilliseconds / (60 * 60 * 1000);
    long diffDays = timeDifferenceMilliseconds / (60 * 60 * 1000 * 24);
    long diffWeeks = timeDifferenceMilliseconds / (60 * 60 * 1000 * 24 * 7);
    long diffMonths = (long) (timeDifferenceMilliseconds / (60 * 60 * 1000 * 24 * 30.41666666));
    long diffYears = (long)(timeDifferenceMilliseconds / (1000 * 60 * 60 * 24 * 365));

    if (diffSeconds < 1) {
        return "one sec ago";
    } else if (diffMinutes < 1) {
        return diffSeconds + " seconds ago";
    } else if (diffHours < 1) {
        return diffMinutes + " minutes ago";
    } else if (diffDays < 1) {
        return diffHours + " hours ago";
    } else if (diffWeeks < 1) {
        return diffDays + " days ago";
    } else if (diffMonths < 1) {
        return diffWeeks + " weeks ago";
    } else if (diffYears < 12) {
        return diffMonths + " months ago";
    } else {
        return diffYears + " years ago";
    }
}   

因为这个问题用Scala做了标记，

import scala.concurrent.duration._
val diff = (System.currentTimeMillis() - oldDate.getTime).milliseconds
val diffSeconds = diff.toSeconds
val diffMinutes = diff.toMinutes
val diffHours = diff.toHours
val diffDays = diff.toDays

在java中有一个简单的方法来做到这一点

//创建一个实用方法

public long getDaysBetweenDates(Date d1, Date d2){
return TimeUnit.MILLISECONDS.toDays(d1.getTime() - d2.getTime());
}

该方法将返回两个日期之间的天数。您可以使用默认的java日期格式，也可以轻松地从任何日期格式转换。
