NCK segment

The NCK segment is used to allow the various applications on the network to synchronize their system clocks (system date and time). Usage Notes: If this message is to be used to automatically reset/correct system clocks, it is recommended that the system or administrative personnel initiating the NMQ with the NCK segment have the authority to correct the clock (system date and time) for the other systems on the network. This is important in order to avoid the obvious confusion of multiple systems attempting to resynchronize each other's clocks.

Count the pipes to find a field, and count the empty ones too: an empty field still holds its place.

This page carries the NCK field table as published and nothing beyond it. The field notes, vendor behaviour, FHIR mapping and parsing guidance that thePID page has are still to be written for NCK.
