一、概述

在NX二次开发过程中，我们为了效率经常会进行Open C的计时统计，这个实例可用于收集关于Open C的计时信息程序，并且在计时测试中很有用。该实例通过UF_begin_timer启动一个计时器，创建一个块，然后调用UF_end_timer来停止，统计建模时长，并将cpu_time和real_time进行窗口显示以及将信息保存到D:\\GetRunningTime.txt中。当然在复杂的案例中多个计时器可以在任何时间处于活动状态，也可以有几个子计时器单独计时子操作。

二、实现的功能

1、统计创建块的cpu时长和运行总时长；

2、将信息在信息窗口中显示并进内容保存到D:\\GetRunningTime.txt中。

三、代码实现以及详细解析
