[time-nuts] purpose of time of day display units

Two reasons that come to mind are:
  Displaying distributed time to distant sites from some master.
  Readability at a distance.

> Hi, looking at pictures of various time metrology equipment setups for best practices and inspiration, I have commonly seen time of day display unit(s) installed in racks containing processing or time transfer equipment, e.g., http://www.xyht.com/wp-content/uploads/2015/05/Powers_Master_Clock.jpg. All that these units do is merely display the time of day and sometimes the date, typically by means of seven segment LED displays, of the time code inputted to them (typically IRIG-B, I'm guessing).  Any ideas why such a unit is necessary when one can simply look at the time displayed by timing receivers and time code generators (and even some standards), and the interface of some fusor, defined in this context as a system which performs timing data fusion (by implementing a paper clock or a more primitive algorithm) and timekeeping, either by means of a direct shell, or via something like NTP?
