I don't know the details. It looks to me as if these would be the fours 
selections that make sense (12 vs. 24 hours, and 0 vs. 1 index origin).

However, what doesn't make sense to me here is that while the 
distinction of origin is made by upper vs. lower case (0 origin: H, K;
1 origin: h, k), the distinction between 12h and 24h is mixed up (12 
hours: h, K; 24 hours: H, k).

I wonder who came up with this, or if it is a mistake.

Regards,    Martin.
