Time Reference Message Fields
The Time Reference message is used to provide a midnight reference point for recipients of the feed. It is sent whenever the system starts up and when the system crosses a midnight boundary. All subsequent Time messages for the same unit will the use the last Midnight Reference until another Time Reference message is received for that unit. The Time Reference message includes the Trade Date, so most other sequenced messages will not include that information.
Time Reference messages will be included in a spin response.
