它就是让seconds获取了当前的系统时间。不过这个时间是以秒存放的。需要使用，localtiome（）函数将其转换成时间日期格式。存放在结构体timeinfo中。然后后面的就是让hour存放当前的时针值，min是分针值。比如，现在是15：30 那么time（）后，seconds里是1970年1月1日0小时0分0秒到当前时间经过了多少秒...

Since one century is equal to 3,155,695,200 seconds, you can use this simple formula to convert: seconds = centuries × 3,155,695,200 The time in seconds is equal to the time in centuries multiplied by 3,155,695,200. For example,here's how to convert 5 centuries to seconds using ...
