You now know how to change the date and time on your Raspberry Pi and how to synchronize the clock from several Linux computers on the same network. My book: Master your Raspberry Pi in 30 days.15 best operating systems for Raspberry Pi (with pictures).25 awesome Raspberry Pi project ideas at home.The NTP daemon will fix the delay step by step.īut if you want to fix it now, you can use: sudo service ntp stop It confirms that the NTP server is working fine. NTPDate is an additional command you can install and use to force time synchronization.Ĭheck your current time delay compared to a server: sudo ntpdate -q 0.us. NTP has fewer commands than timedatectl as everything is in the configuration file.īut you can use this one to manage the ntp server daemon: sudo service ntp status | start | stop | restart NTPDate If you want to use your Raspberry Pi as an NTP server, it’s also in this file that you can change the server configuration (restrict access, broadcast time, etc.). You can edit it to set a new server for time synchronization (lines beginning with “pool”). The configuration file for NTP is available here: /etc/ntp.conf. You need to install it with apt: sudo apt install ntp NTP configuration NTP configuration NTP installationĪs I said, NTP is not available by default on Raspberry Pi OS. I’m not sure to understand all the differences between both and why they are moving to timedatectl.īut in my mind, I think that timedatectl is for clients, easy to use and configure out of the box.Īnd NTP is probably better on a server, to sync time with it and have more configuration options. Even if Debian and Ubuntu are replacing it with timedatectl on new versions, it’s still a common software on Linux systems. The other way to do time synchronization on Linux is to use NTP. ![]() Time synchronization on Raspberry Pi: NTP NTP introduction Comment out the line starting with FallbackNTP and replace default servers with your time servers (on the Internet or from the local network).įallbackNTP=0.us. 1.us.Ī reboot might be necessary to update the configuration, but your date and time will now be synchronized with the servers defined in this configuration file.Open the configuration file: sudo nano /etc/systemd/nf.H ere is how to configure the time synchronization with a server by using timedatectl: Sync time with a server: the Timedatectl configuration file That’s it, you now know the basic timedatectl commands. Note: you may need to reboot the Raspberry Pi to apply this change (see comments). ![]() It’s a 30-day challenge from beginner to master, with step-by-step tutorials and many projects to practice along the way. – NTP: classic way to do this on Linux, for more compatibility with other systems.Īnd finally, I’ll give you other useful commands for date and time on Raspberry Pi.īy the way, if you are really interested in improving your skills on Raspberry Pi, I highly recommend checking out my e-book here. – Timedatectl: included out of the box, pretty easy to configure. I’ll share the two ways of doing this on a Raspberry Pi: I’ll explain how time synchronization works on Linux and how to configure it the way you want. The NTP service can also be installed if needed. Servers can be updated in the configuration file, located at /etc/systemd/nf. On a new installation, a Raspberry Pi uses timedatectl for time synchronization. Do you have issues with the time configuration on Raspberry Pi? Or maybe you want to sync the time with another server? In this post, I’ll teach you all you need to know about time synchronization on Raspberry Pi (and on Linux in general). ![]()
