Convert Time Stamp from rosbag(Topic) to Understandable Format Y/M/D H:M:S
Hi someone would you know what the following TimeStamp means? and how to convert it to seconds or other understable format such year/month/day Hour:Minutes:Seconds?
I have a car-robot that has driven 80 meters in about 1 min of simulation. However when I recorded the rosbag I had the: First Timestamp =1,63277521885359E+018 and the Last TimeStamp from this topic (odom) = 1,63277529735619E+018
I do not know to convert this data to an understandable format such as Y/M/D H:M:S Some tool makes the trick? Or some Python Library such as DateTime (how to specific use, suitable class to apply?)
I have done some research herehttps://discourse.ros.org/t/times... But these steps seem too complex http://wiki.ros.org/rosbag/Cookbook
In addition, I got another column in my rosbag called field.header.sec that intuitively should return the seconds. But assessing this data again. The first/end data are:
T0 = 7348 TF = 8036
Subtracting these values I have 688 seconds = 11 minutes. And this is Not realistic because I have killed the simulation and the rosbag after 2 minutes( max) and the car in the simulation achieved the goal after 1 min, not 11 minutes.... I wonder how to understand and convert the TimeStamp extracted from rosbags. If someone could help me, I would be very grateful

Did you cross-post this to ROS Discourse here?
yes sorry I am trying to get as much ideas as possible to help on this issue.
That's not how it works, and is actually pretty annoying. At best it leads to duplicated answers. In most cases it leads to wasted effort.
And it's not such a special problem. The Q&As I've linked in my answer already discuss this, and they're years old.
Ok....I respect your point of view...because actually there are different channels, different experts that will visualize...so..., I think different..but ok.
Could you take a look at my own answer below, please? I am trying to figure out what is wrong with the code.
It's not just my point of view: https://en.wikipedia.org/wiki/Crosspo...
Hummm ok I got the idea @gvdhoorn, I have tooken a quick read...so much rules to be aware...not easy. But thanks to share these rules to me. I will try to follow all of them. Additionally let me ask you, I have edited the question on ROS Discourse, and instead put the whole question as here I have just put this link of ROS Answers for other ROS users visualize. Would this be the right manner or not? I mean if I wish that some question be visualized by different communities...which is the right way?? And thanks again for your answer!! It saved my time!
