Hi, I am trying to process some bag files and, while I am able to get the timestamp for each message, I am not able to get the actual time the message was received. Is it possible to get it? I am using the python api and I could not find any documentations, any help is really appreciated! Thanks for your help!

You can get that information using the rosbag API. Take a look at the rosbag Cookbook wiki page. The time is in the tuple returned from read_messages().
