As opposed to the DateSerial or the DateValue function, where serial date values result in days relative to a fixed date, you can calculate with the values that are returned by the TimeValue function, but you cannot evaluate them.
在 DateSerial 或 DateValue 函数中，顺序日期值的计算结果为与某个固定日期相差的天数，但对于 TimeValue 函数，您只能利用它的返回值来进行计算，而不能计算返回值本身。
