In the TimeSerial function, you can pass individual parameters (hour, minute, second) as separate numerical expressions. For the TimeValue function, however, you can pass a string as a parameter containing the time.
在 TimeSerial 函数中，可以用独立的数字表达式来传送单个参数 (hour、minute、second)；而在 TimeValue 函数中，则用含有时间的参数来传送字符串。
