计算你所指定的两个时间（通过Calender类型传入），之间所间隔的天数。指定一个时间的话则计算你指定的时间到当前时间的天数，在进度控制方面的程序中可能有用哦(Calculation of your two time specified (through the Calendar type imported), the interval between the number of days. Specify a time, then the calculation of the time you specify to the current time the number of days, in the progress of control procedures may be useful Oh)
