解决方案：terminate called after throwing an instance of ros::TimeNotInitializedException

在ROS中使用ros::Time和ros::Duration时出现了如下错误：

terminate called after throwing an instance of 'ros::TimeNotInitializedException'
  what():  Cannot use ros::Time::now() before the first NodeHandle has been created or ros::start() has been called.  If this is a standalone app or test that just uses ros::Time and does not communicate over ROS, you may also call ros::Time::init()
已放弃 (核心已转储)

解决方案：

在建立ros::Time和ros::Duration对象之前，采用ros::Time::init();语句进行初始化。
