2019-06-26 22:00:47 -0500	marked best answer	Time Sync between rosserial on Windows & RosMaster on linux The problem is: how can I sync time between rosserial node on Windows xp and RosMaster on Linux. A robot controlled by WinXP is communicating to ROSMaster on a ubuntu14.04. Everything was ok until I relized that there is always a 30+- seconds delay between the ros::time::now() output on two different machines. Based on the posts I have read before, ros nodes use local time to do ros::time::now(). I know I can estimate and offset this delay on master side. But I want to take the transmission delay into account. So...Thanks for reading this. And is there an easy way to sync the timestamp from both message senders?
