Ha, the scientists would do well to avoid promoting exact correspondences between the models used by everyday people and their own specialist ones. Somewhere there will always be an exception or a divergence of practices between these groups and even within each of them. Case in point: these instruments were used by a substantial number of people for a somewhat lengthy period of time. Even if nobody were to use these instruments again, the interpretation of surviving historic documents which reference a time of day would forever benefit from the ability to understand what those times mean. As an aside, a fascinating detail of the near-ubiquitously adopted iCalendar RFC, an Internet Engineering Task Force (IETF) standard for encoding events for calendar software, is a consequence of its development having been predominantly influenced by the Gregorian system. There are major calendar software systems which, in compliance with the IETF standard, are incapable of encoding religious holidays in terms of lunar calendar definitions, resulting in the use of calendar events that approximate the holidays' start and end times instead.
