给定两个Date对象,比较它们的时间部分之间的差异,完全忽略年,月和日,有什么好方法？

这与这个问题完全相反.

更新:这是未来参考的最终代码:

private long differenceBetween(Date currentTime, Date timeToRun)
{
    Calendar currentCal = Calendar.getInstance();
    currentCal.setTime(currentTime);

    Calendar runCal = Calendar.getInstance();
    runCal.setTime(timeToRun);
    runCal.set(Calendar.DAY_OF_MONTH, currentCal.get(Calendar.DAY_OF_MONTH));
    runCal.set(Calendar.MONTH, currentCal.get(Calendar.MONTH));
    runCal.set(Calendar.YEAR, currentCal.get(Calendar.YEAR));

    return currentCal.getTimeInMillis() - runCal.getTimeInMillis();
}
