Hi there, I am new to the ROS and its community. I am looking for a function that can convert the ROS time to the boost::posix_time::ptime. Does anybody know about such function? I found an answer here, which is close to what I am looking for. However, when I use this .toBoost() function, an exception is thrown, " Year is out of valid range: 1400..100000". Also, I couldn't find the function .toBoost() in ros:Time class reference.

If anybody knows about such function then please let me know. Any suggestions/remarks are most welcomed! [edit 1] : example: ROS timestamp(1520004209.448167176) to boost time --> results into the error.

Thank you very much,

" Year is out of valid range: 1400..100000"

that would seem to suggest something is wrong with your timestamps. Can you add some examples of stamps you try to convert to your question text? Use the edit button/link.

I've updated your question title, as there is a known conversion (#q251966) but you're encountering errors trying to use it. That would seem to be the real problem here.

The code is here. If you duplicate that and see what is being passed to the boost::posix_time::ptime::from_time_t(..) and nanoseconds(..) function?

Thank you gvdhoorn for the link. It is very useful.

Have you figured out what's going wrong with your conversion?

In the code, a random string was passed to this function which might be the reason for this error. However, I didn't test it as I removed the need of this conversion from the code base.
