(Note that this still 65overrides your core functions.) Access these fields as 66variables named with a preceding C<tm_> in front their method names. 67Thus, C<$tm_obj-E<gt>mday()> corresponds to $tm_mday if you import 68the fields. 69 70The ctime() function provides a way of getting at the 71scalar sense of the original CORE::localtime() function. 72 73To access this functionality without the core overrides, 74pass the C<use> an empty import list, and then access 75function functions with their full qualified names. 76On the other hand, the built-ins are still available 77via the C<CORE::> pseudo-package. 78 79=head1 NOTE 80 81While this class is currently implemented using the Class::Struct 82module to build a struct-like class, you shouldn't rely upon this. 83 84=head1 AUTHOR 85 86Tom Christiansen 87
