Synchronize your Linux system time and clock speed

The clock speed not only can update the system clock from the NTP server, but it can also calculate the clock frequency and manage the system time accordingly.

Many people who want to keep an accurate computer clock use network time Protocol (NTP) to set their clocks at the same times as the atomic clocks. NTP is a way to ensure that all computers in a network operation have exactly the same time, so that they can help oversee the recording of files and routine automated maintenance work, and so on.

However, if you have a fairly large network, NTP can provide a considerable amount of traffic to keep the clock updated. In a way, it needs to operate regularly to adjust the individual clock frequencies on different computers. So unless you've set up your NTP server for your network, it won't be able to generate more traffic than you expect.

The other option is D. J. Bernstein clock Speed program. It can not only update the system clock from the NTP server, but it can also calculate the clock frequency and manage the system time accordingly.

With the clock speed, you only need to sync the NTP server once in a while, and this occasional time can even be once a year.

First, download the clock speed from the network, compile and install. Then, use the Sntpclock tool to see the difference between the remote clock and the local clock, as shown below. (Use the IP address of the remote NTP server instead of 1.2.3.4).

# Sntpclock 1.2.3.4 | Clockview

This shows that the current time is the time displayed with the NTP server. Perform an operation to update the local clock to the same time as the NTP server:

# Sntpclock 1.2.3.4 | Clockadd

Next, run the clock speed by adding the following to the/etc/rc.d/rc.local, just as daemon this daemon.

The installation file for the clock speed further provides information for viewing and adjusting the system clock after a number of days or weeks. It will sync your local and remote clocks in a few minutes every other century. At this point, a yearly check time is very reasonable.
