Which is OK.  %I alone can be interpreted as 0 hours or 12 hours (12am
or 12pm).  And you are confusing input format specification [1,12]
with the allowed values for tm_hour (defined in <time.h>).

Which I argue is acceptable.  The input for %y is up to two digits
wide.  I know that other systems do this differently but there is
nothing written which says this is the only or even right
interpretation.

Same.

Leading zeros refers to the zeros you can add before the digit for
numbers < 10.

This is not really a bug but you can change it if you want.  Feel
free.
