替代使用平台的时间程序，你应该使用的roscpp时间程序访问当前时间，它能让模拟时钟以及普通时钟的时间无缝工作。. 获取当前时间. 函数：ros::Time::now () 作用：得到ros::Time实例化的当前时间. 示例：. ros::Time begin = ros::Time::now(); Time zero（时间0）. 使用模拟时钟 .ros::Time current_expected. In a perfect world, this is when the current callback should have been called ; ros::Time current_real. When the current callback is actually being called (ros::Time::now() as of immediately before calling the callback) ros::WallTime profile.last_duration.

1、Time and Duration. 本文总结了 roscpp 给我们提供的时间相关的操作。. 具体来说，roscpp 里有两种时间表示方法：时刻 (ros::Time) 和时长 (ros::Duration)。. 其中Duration可以是负数。. Time和Duration拥有一样的成员：. 要使用 Time 和 Duration，需要分别 #include 和 #include .
ROS has builtin time and duration primitive types, which rosserial provides as the ros::Time and ros::Duration classes, respectively. A Time is a specific moment (e.g. "today at 5pm") whereas a Duration is a period of time (e.g. "5 hours"). Durations can be negative. Times and durations have identical representations: unsigned long secs. roslib.rostime.Time --+. Time. Time represents the ROS 'time' primitive type, which consists of two integers: seconds since epoch and nanoseconds since seconds. Time instances are mutable. The Time.now () factory method can initialize Time to the current ROS time and from_sec () can be used to create a Time instance from the .
Returns whether or not the current time is valid. Time is valid if it is non-zero. Definition at line 324 of file src/time.cpp. Time ros::Time::now. (. ) static. Retrieve the current time. If ROS clock time is in use, this returns the time according to the ROS clock.
The time abstraction can be published by one source on the /clock topic. The topic will contain the most up to date time for the ROS system. If a publisher exists for the topic, it will override the system time when using the ROS time abstraction. If /clock is being published, calls to the ROS time abstraction will return the latest time .Time and Duration. ROS has builtin time and duration primitive types, which rospy provides as the rospy.Time and rospy.Duration classes, respectively.

The Time.now () factory method can initialize Time to the current ROS time and from_sec () can be used to create a Time instance from the .In order for a ROS node to use simulation time according to the /clock topic, the /use_sim_time parameter must be set to true before the node is initialized. This can be done in a launchfile or from the command line. If the /use_sim_time parameter is set, the ROS Time API will return time= 0 until it has received a value from the /clock topic.

説明. Current Time ブロックは、現在の ROS 時間またはシステム時間を出力します。 ROS 時間は、コンピューターのシステム クロック、または ROS ノードでパブリッシュされる /clock トピックに基づきます。. このブロックを使用して、接続している ROS ノードとシミュレーション時間を同期させます。
