  40  
  41  Time::gmtime - by-name interface to Perl's built-in gmtime() function
  42  
  43  =head1 SYNOPSIS
  44  
  45   use Time::gmtime;
  46   $gm = gmtime();
  47   printf "The day in Greenwich is %s\n", 
  48      (qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ $gm->wday() ];
  49  
  50   use Time::gmtime qw(:FIELDS);
  51   gmtime();
  52   printf "The day in Greenwich is %s\n", 
  53      (qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ $tm_wday ];
  54  
  55   $now = gmctime();
  56  
  57   use Time::gmtime;
  58   use File::stat;
  59   $date_string = gmctime(stat($file)->mtime);
  60  
  61  =head1 DESCRIPTION
  62  
  63  This module's default exports override the core gmtime() function,
  64  replacing it with a version that returns "Time::tm" objects.
  65  This object has methods that return the similarly named structure field
  66  name from the C's tm structure from F<time.h>; namely sec, min, hour,
  67  mday, mon, year, wday, yday, and isdst.
  68  
  69  You may also import all the structure fields directly into your namespace
  70  as regular variables using the :FIELDS import tag.  (Note that this
  71  still overrides your core functions.)  Access these fields as variables
  72  named with a preceding C<tm_> in front their method names.  Thus,
  73  C<$tm_obj-E<gt>mday()> corresponds to $tm_mday if you import the fields.
  74  
  75  The gmctime() function provides a way of getting at the 
  76  scalar sense of the original CORE::gmtime() function.
  77  
  78  To access this functionality without the core overrides,
  79  pass the C<use> an empty import list, and then access
  80  function functions with their full qualified names.
  81  On the other hand, the built-ins are still available
  82  via the C<CORE::> pseudo-package.
  83  
  84  =head1 NOTE
  85  
  86  While this class is currently implemented using the Class::Struct
  87  module to build a struct-like class, you shouldn't rely upon this.
