      We consider the feature is partially done for PI#19, the remaining parts will be done in PI#20 under new feature: https://jira.skatelescope.org/browse/SP-3640

      The feature demo for the completed part of this feature is written here:
      https://docs.google.com/presentation/d/1loPvGwgPqn5GKBD-kEszG1Hm_uQxiVtnkkkK5EBGXsE/edit#slide=id.g112dcb28055_0_0

      The feature demo is registered as an offline demo in OMC System Demo 19.5 https://confluence.skatelescope.org/display/SE/2023-08-17+OMC+ART+System+Demo+19.5

    Description

      Currently the correlator visibility SPEAD output packets do not contain a valid timestamp.

      This feature is to propagate and calculate an accurate timestamp for the correlator visibilities that relate to the SPS timestamps

      Appropriate correlator software and firmware will be developed to enable the highest accuracy timestamps to be placed for each visibility output product.
