Hello guys, I'm having a problem with ROS Time, I need for a protect the exact Time and the exact Hour at which some event happened. I tried with ros time, but I don't see any equivalences between the double number 1486371808.656735126 and the Date and Hour Mon Feb 6 04:03:32 COT 2017.

Does anyone have suggestions?

Thank you very much

if(m_Slots.at(c).getState() == true){
    ROS_INFO("The sensor in the slot %s was ACTIVATED", m_Slots.at(c).getID().c_str());
    double timeDouble = ros::WallTime::now().toSec()*1000.;
    std::ostringstream sstream;
    sstream << timeDouble;
    std::string timeString = sstream.str();
    string message = "rosrun sound_play say.py 'La herramienta fue dejada'"+timeString;
    std::cout << message << std::endl;
    //system("rosrun sound_play say.py 'La herramienta fue dejada'");
    //TODO definir hora de recepcion del usuario en la herramienta con getTimePointActivated
}else{
    ROS_INFO("The sensor in the slot %s is DEACTIVATED", m_Slots.at(c).getID().c_str());
    //system("rosrun sound_play say.py 'The tool has been taken'");

The time is in Unix time, seconds since 1970. You can transform it to a more readable format with the functions in <ctime> for C++ or the time module in Python.

Thank you very much, <ctime> worked perfectly.
