Converting ros::Time to C++ string

edit

You probably want to use the ros::Time::now().toSec() result, which is a double.

http://docs.ros.org/latest/api/rostim...

Then you can convert that double to a string with std::string to_string.

You could use strftime to convert the double to many different string formats as well.
