Ada 83 didn't have a "date format". String representations of dates were left up
to the programmer. What it did have was Calendar.Time, which could be created
from Year, Month, and Day numbers, each clearly labeled with what it
represented, or queried/decomposed to obtain Year, Month, and Day numbers, again
clearly labeled.
For the early 1980s, it was somewhat prescient in avoiding 2-digit years,
something I recall liking when I first encountered the language.
