编译警告：warning: Clock skew detected. Your build may be incomplete.

        在编译darknet_ros程序时，遇到如下警告：

make[2]: Warning: File 'darknet_ros/darknet_ros/CMakeFiles/darknet_ros_lib.dir/depend.make' has modification time 25801 s in the future
make[2]: warning:  Clock skew detected.  Your build may be incomplete.

[100%] Built target darknet_ros

截图如下：

分析：出现这个警告是由于时钟不同步导致的，即系统时间比文件修改时间早，Windows和Linux系统切换可能会出现这个问题。

解决方案： 依次执行下列指令即可

$ find . -type f | xargs -n 5 touch
$ catkin_make clean
$ catkin_make
