I didn't think the efficiency benefit. I hoped that I get an
meintainabillity benefit. I think "string that represents date
in C to Ruby's Time" conversion is primitive conversion such as
int in C to Ruby's Integer, char * in C to Ruby's String and so
on. So, I think the conversion is "a direct wrapper of C API".
And it is natural that I moved the conversion to SWIG layer.

I hope my explain answers your question, Max.
