Hi Ashesh

Apart from using stdio.h to write code to read a file of strings formatted like trajectory_msgs::JointTrajectory. You could try writing rostopic messages to your node. Or your own YAML file that contains the information your trajectory requires and uploading it to the parameter server, then using a node to read the parameter server and format a JointTrajectory msgs from the information there and publishing it.

As for converting an integer or float to a duration type you can save your duration as a float or integer and use:

ros::Duration(24*60*60);

with the time in seconds in the brackets. And your stamp values in your header you just use:

header.stamp = ros::Time::now();

before you publish it.

hope it helps
