I was just wondering, if I want to write a while loop which says while x seconds hasn't reach execute this statement, how would I go about it? I tried using while(ros::Duration(x).sleep()){ .... } but it doesn't work. also, tried creating a counter but there is no way to measure the count in seconds

Example code that should do what you want:

ros::Time start_time = ros::Time::now();
ros::Duration timeout(2.0); // Timeout of 2 seconds
while(ros::Time::now() - start_time < timeout) {
  // do your stuff

it's not working for me if I give 2 for a timeout the loops do not stop for milliseconds. I tried giving 100 and the same result. but when I gave 200 it remains for some time. but I cannot find the relationship
