我实施了一款秒表，可以很好地运行，而无需考虑不应将银行假期和周末计入总时间。我一直在寻找一些开放源代码库，可以获取经过的时间，经过一个开始时刻，一个结束时刻以及一组银行假期(不计入周末)。唯一使我更轻松的库是net.sf.jtemporal，但是我仍然需要扩大功能。
谁能告诉我是否有一些有用的库来获取所需的功能？

谢谢

我们也只计算营业时间吗？上午9点至下午3点？还是一天24小时？

正如我在这里提到的，最好和最简单的方法可能是创建一个包含每天信息的表(从开始/银行假期开始的工作日计数等；每天一行=每年365行)，然后仅使用计数功能/选择正确。

我怀疑我们能找到具体的东西。但是创建我们自己的逻辑很容易。这是一些伪代码...

private long CalculateTimeSpan(DateTime BeginDate, DateTime EndDate, ArrayList<DateTime> BankHollidays)
{
    long ticks = 0;
    while (BeginDate <= EndDate) // iterate until reaching end
    {
        if ((BeginDate is holliday?) || (BeginDate is Weekend?))
             skip;
        else
             ticks += (24*60*60*1000);

        BeginDate = BeginDate + 1 day; // add one day and iterate
    }

    return ticks;
}

我们应该看看Joda Time。它是一种比Java附带的日期/时间API好得多的日期/时间API。

我认为这将是我们正在寻找的有效解决方案。它计算经过的时间(假设一个工作日有24小时)，而不计算银行假期和周末的时间：

/**
 * Calculate elapsed time in milliseconds
 * 
 * @param startTime
 * @param endTime
 * @return elapsed time in milliseconds
 */

protected long calculateElapsedTimeAux(long startTime, long endTime) { 
    CustomizedGregorianCalendar calStartTime = new CustomizedGregorianCalendar(this.getTimeZone());
    CustomizedGregorianCalendar calEndTime = new CustomizedGregorianCalendar(this.getTimeZone());
    calStartTime.setTimeInMillis(startTime);
    calEndTime.setTimeInMillis(endTime);
    long ticks = 0;

    while (calStartTime.before(calEndTime)) { // iterate until reaching end 
        ticks = ticks + increaseElapsedTime(calStartTime, calEndTime);
    }

    return ticks;
}

private long increaseElapsedTime(CustomizedGregorianCalendar calStartTime, CustomizedGregorianCalendar calEndTime) {
    long interval;
    long ticks = 0;

    interval = HOURS_PER_DAY*MINUTES_PER_HOUR*SECONDS_PER_MIN*MILLISECONDS_PER_SEC; // Interval of one day

    if ( calEndTime.getTimeInMillis() - calStartTime.getTimeInMillis() < interval) {
        interval = calEndTime.getTimeInMillis() - calStartTime.getTimeInMillis();
    }

    ticks = increaseElapsedTimeAux(calStartTime, calEndTime, interval);
    calStartTime.setTimeInMillis(calStartTime.getTimeInMillis() + interval);

    return ticks;
}

protected long increaseElapsedTimeAux(CustomizedGregorianCalendar calStartTime, CustomizedGregorianCalendar calEndTime, long interval) {
    long ticks = 0;

    CustomizedGregorianCalendar calNextStartTime = new CustomizedGregorianCalendar(this.getTimeZone());
    calNextStartTime.setTimeInMillis(calStartTime.getTimeInMillis() + interval);

    if ( (calStartTime.isWorkingDay(_nonWorkingDays) && calNextStartTime.isWorkingDay(_nonWorkingDays)) ) { // calStartTime and calNextStartTime are working days
        ticks = interval;

    }
    else {
        if (calStartTime.isWorkingDay(_nonWorkingDays)) { // calStartTime is a working day and calNextStartTime is a non-working day
            ticks = (calStartTime.getNextDay().getTimeInMillis() - calStartTime.getTimeInMillis());
        }
        else {
            if (calNextStartTime.isWorkingDay(_nonWorkingDays)) { // calStartTime is a non-working day and calNextStartTime is a working day
                ticks = (calNextStartTime.getTimeInMillis() - calStartTime.getNextDay().getTimeInMillis());
            }
            else {} // calStartTime and calEndTime are non-working days
        }
    }

    return ticks;
}
