Precision Time Protocol (PTP) is used to synchronize clocks in a network. When used in conjunction with hardware support, PTP is capable of sub-microsecond accuracy, and is more accurate than Network Time Protocol (NTP).
[IMPORTANT]
====
If your `openshift-sdn` cluster with PTP uses the User Datagram Protocol (UDP) for hardware time stamping and you migrate to the OVN-Kubernetes plugin, the hardware time stamping cannot be applied to primary interface devices, such as an Open vSwitch (OVS) bridge. As a result, UDP version 4 configurations cannot work with a `br-ex` interface.
====
You can configure `linuxptp` services and use PTP-capable hardware in {product-title} cluster nodes.
Use the {product-title} web console or OpenShift CLI (`oc`) to install PTP by deploying the PTP Operator. The PTP Operator creates and manages the `linuxptp` services and provides the following features:
