+Time Synchronization
+~~~~~~~~~~~~~~~~~~~~
+
+The system operator can run a PTP (Precision Time Protocol) client application
+to synchronize the time on the network card in ACC
+(and optionally the time on the system) to the PTP primary.
+
+IDPF PMD supports PTP client applications that use the DPDK IEEE 1588 API
+to communicate with the PTP primary clock.
+Note that PTP client application needs to run on PF in ACC.
