* This method is similar to strftime() function defined in ISO C and POSIX.
4511
* Several directives (%a, %A, %b, %B, %c, %p, %r, %x, %X, %E*, %O* and %Z)
4512
* are locale dependent in the function.
4513
* However this method is locale independent since Ruby 1.9.
4514
* So, the result may differ even if a same format string is used in other
4515
* systems such as C.
