// 最后修改时间2002-1-28 1：35
// 此函数求解决返回时间显示格式问题。包括date()函数的所有格式，默认的$type为最常用的类型
// 除了$year,$month,$day,$hour,$minute,$second;添加了$week（周），$zone(一年中的第几天)，$numMonth（当前月份的天数）
// 其中默认的都为最常用的格式
// 特点，在时间处理中用得最多的是mktime，这里设置mktime可以按照习惯输入（年，月，日）显示
// mktimeY();mktimeW();mktimeM();mktimeD();可以方便设置一个时间相隔y年，n月，在mysql检索中方便使用
// subTime();函数可以方便求得两个时间相差的天数，周等
