Explain the meaning of chrony stratum

Chrony stratum is a metric used to synchronize the clocks of the devices using NTP (Network Time Protocol). It is an integer value that represents the time difference between two devices in NTP. The aim of Chrony is to synchronize clocks as accurately as possible on a system while minimizing errors.

Chrony's stratum value ranges from 0 to 15 (as per RFC 3936). The lower the stratum, the more accurate it is. A stratum of 1 is less accurate than a stratum of 0. If a device's clock is not synchronized, then it will not be able to synchronize the other devices that are lower in the chrony's hierarchy. A device can have a stratum of 15, meaning it is not synchronized. A stratum of 16 would be incremented if its clock changes based on system time or the device no longer synchronizes.

Therefore, a lower value in stratum means more accurate sync in chrony.

Explain the meaning of chrony stratum

In the world of computer networking and time synchronization, a stratum is a term used to describe the distance of a particular device from the reference clock in a network. The reference clock, also known as a stratum 0 device, is typically a highly accurate time source like a GPS receiver or an atomic clock.

Chrony is a software program that is used to synchronize the system clock with a remote time server using the Network Time Protocol (NTP). Chrony is designed to be more accurate and efficient than traditional NTP implementations, especially in systems that are not always connected to the internet or have intermittent connections.

When Chrony is running, it will determine the stratum level of your system based on its connection to other time sources. If your system is synchronized directly with a stratum 1 time server (i.e., a device that is directly connected to a stratum 0 device), then your system is considered to be operating at stratum 2. If your system is synchronized with a stratum 2 time server, then it is operating at stratum 3, and so on.

In summary, stratum refers to the level of a device in the time synchronization hierarchy, and Chrony uses this hierarchy to synchronize the system clock with remote time servers. The lower the stratum number, the closer the device is to the reference clock, and the more accurate its time synchronization is likely to be.
