Refactor code from previous commit.

* Check if offset is actually an error code and attempt to compensate
  At the very least don't use it as an offset (would be bad).
* Write to the output string directly instead of copying a temp string.
* Add a ToDo to check if day of week should go after time for locale
* Replace hardcoded 64 in GetCurrentDate().
