(Note that this 70still overrides your core functions.) Access these fields as variables 71named with a preceding C<tm_> in front their method names. Thus, 72C<$tm_obj-E<gt>mday()> corresponds to $tm_mday if you import the fields. 73 74The gmctime() function provides a way of getting at the 75scalar sense of the original CORE::gmtime() function. 76 77To access this functionality without the core overrides, 78pass the C<use> an empty import list, and then access 79function functions with their full qualified names. 80On the other hand, the built-ins are still available 81via the C<CORE::> pseudo-package. 82 83=head1 NOTE 84 85While this class is currently implemented using the Class::Struct 86module to build a struct-like class, you shouldn't rely upon this. 87 88=head1 AUTHOR 89 90Tom Christiansen 91
