经过时间在不考虑Java的周末和节假日

Question

我实现了没有考虑到银行假日和周末不应该在总时长进行计数正常工作秒表。我一直在寻找一些开源的图书馆，在那里我能得到所经过的时间，通过启动瞬间，结束时刻和一组银行假期（周末不计入）。这让我更容易的事情，唯一库是net.sf.jtemporal，但我还是要放大的功能。谁能告诉我，如果有一些有用的库来获得想要的功能？

Answer 1

正如我刚才所说there，可能是最好的和最简单的方法是创建一个包含有关每一天的信息表（从开始/银行假日，等工作日算，每天每一年= 365行一列），然后只用计数功能/适当选择。

Answer 2

我怀疑你能找到的东西，具体的。但它是很容易建立自己的逻辑。下面是一些伪代码...

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;
}

Answer 3

你只算银行营业时间吗？上午9时 - 下午3点？抑或是每天24小时？

Answer 4

你应该看看Joda Time。这是一个更好的日期/时间API比包含Java中的一个

Answer 5

我认为这将是你的正在寻找一个有效的解决方案。它计算所经过的时间（考虑到一个工作日有24个小时）没有算在银行假日和周末：

/**
 * 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;
}
