(Note that this still +overrides your core functions.) Access these fields as +variables named with a preceding C<tm_> in front their method names. +Thus, C<$tm_obj-E<gt>mday()> corresponds to $tm_mday if you import +the fields. + +The ctime() function provides a way of getting at the +scalar sense of the original CORE::localtime() function. + +To access this functionality without the core overrides, +pass the C<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 C<CORE::> pseudo-package. + +=head1 NOTE + +While this class is currently implemented using the Class::Struct +module to build a struct-like class, you shouldn't rely upon this. + +=head1 AUTHOR + +Tom Christiansen |
