So 7 in 1-year digit register, 1 in 10-year digit register. And it requires 10×(10-year reg) + (1-year reg) be <= 99.
It uses invalid BCD values (2017 = 117 = B7), this is more AmigaOS compatible.

Surprisingly Comspec accepts the date (and it even is printed correctly) if year value is 17 (instead of 117). So Comspec now uses different method.
