Hi Guys,
This is with respect to the [q313094](https://answers.ros.org/question/313094/is-clock-being-published/?comment=313100#post-id-313100), I was able to get rid of the ```/use_sim_time is not set, will not subscribe to simulated time [/clock] topic``` error by following the steps given in [link](http://answers.ros.org/question/298602/).
However as mentioned in the answer, I always need to run the subscriber first then start publishing the message. If I start publishing first then subscriber it doesn't work.
Could you please let me know is there a way I can fix this, so that I can subscribe to the message anytime?
Thank you,
KK
