Yes, infact embedded board doesn't have a button battery, so every reboot means that the date will reset on 1 Jan 1970: for that reason the offset is very high. I'll try chrony to fix this, and I let's you know the result. The output it's the same, both IP and Hostname: 5 May 20:55:46 ntpdate...

Chrony has been working well for us. We have computer 2 on the robot synchronize with computer 1, and computer 1 synchronize with the outside world. The key is to properly set the initstepslew so that at boot time computer steps to the correct time. We have computer 1 set to initstepslew to the...

Hi Kadir, You might also want to look into chrony (http://chrony.tuxfamily.org/). If you search the ros-users archives you'll find a couple of threads on its use. Cheers, Pat On Sun, Feb 6, 2011 at 7:44 AM, kadir <kadirfu@...> wrote: > > Hi Stuart, Tully, > > The problem is...

First of all, it looks like the offset is really, really high between your embedded board and your laptop. You can probably use "chrony" to sync them: http://chrony.tuxfamily.org/ ntp_monitor.py checks against both the remote host, and the computer. If either one of these commands fails, then...

... diagnostic info shown in things like chrony (https://docs.fedoraproject.org/en-US/Fedora/18/html/System_Administrators_Guide/sect-Checking_if_chrony_is_synchronized.html) would be key in allowing the clock skew and frequency skew be automatically calculated by the clock node. I think having a...

... chrony to synchronize the time different 'nodes' are running at, this is because the Pi doesn't have a real time clock, and if your Wifi is not connected to the Internet, the Pi will have the wrong time. Next I suggest you load the following ROS packages into your catkin_ws/src workspace: ROS...
