类属性:
1.Format
输出时是否带HTML换行标签
-html:输出HTML换行标签和文本换行符(默认)
-text:仅输出文本换行符

类方法:
1.Record("Code Name")
统计自上一次调用Record方法至现在的时间(第一次调用时统计声明类时至调用时时间),最后在Statistic中输出

类函数:(即时返回信息)
1.Nonce
输出自上一次调用nonce函数至现在的时间(第一次调用时统计声明类时至调用时时间)
2.Total
输出声明类到现在总时间
3.Statistic
输出所有Record统计信息和总程序时间

实例代码:
 程序代码
Dim objRecord,i,k,j,x

Set objRecord = New ccClsProcessTimeRecorder
objRecord.Format = "html"

For i = 1 To 100000
  x = 2 + 2
Next

Call objRecord.Record("加法")
For j = 1 To 100000
  x = 2 * 2
Next

Call objRecord.Record("乘法")

For k = 1 To 100000
  x = 2 ^ 2
Next

Call objRecord.Record("开方")

Response.Write objRecord.Statistic

输出:
Process Time Record
--------------------------------------
加法 : 0.0625 s
乘法 : 0.0469 s
开方 : 0.1094 s
--------------------------------------
Total : 0.2188 s
