You may also import all the structure fields directly into your namespace as regular variables using the :FIELDS import tag. (Note that this still overrides your core functions.) Access these fields as variables named with a preceding tm_ in front their method names. Thus, $tm_obj->mday() corresponds to $tm_mday if you import the fields.
The gmctime() funtion provides a way of getting at the scalar sense of the original CORE::gmtime() function.
To access this functionality without the core overrides, pass the use an empty import list, and then access function functions with their full qualified names. On the other hand, the built-ins are still available via the CORE:: pseudo-package.
