ada: Fix edge case in Ada.Calendar.Formatting.Time_Of

Before this patch, Ada.Calendar.Formatting.Time_Of executed extra code
when passed a number of seconds equal to the number of seconds in a day.
This caused the result to be off, perhaps because a statement resetting
the number of seconds to zero was missing.

Instead of adding such a statement, this patch removes the special
handling of the problematic case, which gives the intended result.
