Converting ros::Time to C++ string

How can we convert the result of ros::Time::now() into std::string, given that std::string to_string (*) in C++11 doesn't support this conversion ?

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.
