'该函数作用：按指定参数格式化显示时间。
'numformat=1:将时间转化为yyyy-mm-dd hh:nn格式。
'numformat=2:将时间转化为yyyy-mm-dd格式。
'numformat=3:将时间转化为hh:nn格式。
'numformat=4:将时间转化为yyyy年mm月dd日 hh时nn分格式。
'numformat=5:将时间转化为yyyy年mm月dd日格式。
'numformat=6:将时间转化为hh时nn分格式。
'numformat=7:将时间转化为yyyy年mm月dd日 星期×格式。
'numformat=8:将时间转化为yymmdd格式。
'numformat=9:将时间转化为mm-dd格式。

我是最近才看到那个帖的。但是已经不能打开了。
好象被管理员删除了。
所以我才发这个帖的。
希望很多的朋友用到很好的函数。但是自己也想用啊..
