I guess your script subscribes to nav_msgs/Odometry
messages since you said you have a twist output. If you check the documentation of the message you'll find that there are different fields :
std_msgs/Header header
string child_frame_id
geometry_msgs/PoseWithCovariance pose
geometry_msgs/TwistWithCovariance twist
Your script gets the info from the fields pose
and twist
, if you want to get the time you have to check in the field header
, and within the header
there is the field time
.
So in your script you probably have a print function with something like data.pose.pose.position
in it. You just have to add data.header.time
somewhere in your print.
