Time::gmtime - by-name interface to Perl's built-in gmtime() function |

|
|
|
| 45 |
|

|
|
$gm = gmtime(); |
| 47 |

=head1 DESCRIPTION |
| 61 |
|
|
|
| 62 |
|
|
This module's default exports override the core gmtime() function, |
| 63 |
|
|
replacing it with a version that returns "Time::tm" objects. |
| 64 |
|
|
This object has methods that return the similarly named structure field |
| 65 |
|
|
name from the C's tm structure from F<time.h>; namely sec, min, hour, |
| 66 |
|
|
mday, mon, year, wday, yday, and isdst. |
| 67 |
|
|
|
| 68 |
|
|
You may also import all the structure fields directly into your namespace |
| 69 |
|
|
as regular variables using the :FIELDS import tag. (Note that this |
| 70 |
|
|
still overrides your core functions.) Access these fields as variables |
| 71 |
|
|
named with a preceding C<tm_> in front their method names. Thus, |
| 72 |
|
|
C<$tm_obj-E<gt>mday()> corresponds to $tm_mday if you import the fields. |
| 73 |
|
|
|
| 74 |
|
|
The gmctime() function provides a way of getting at the |
| 75 |
|
|
scalar sense of the original CORE::gmtime() function. |
| 76 |
|
|
|
| 77 |
|
|
To access this functionality without the core overrides, |
| 78 |
|
|
pass the C<use> an empty import list, and then access |
| 79 |
|
|
function functions with their full qualified names. |
| 80 |
|
|
On the other hand, the built-ins are still available |
| 81 |
|
|
via the C<CORE::> pseudo-package. |

=head1 NOTE |
| 84 |
|
|
|
| 85 |
|
|
While this class is currently implemented using the Class::Struct |
| 86 |
|
|
module to build a struct-like class, you shouldn't rely upon this. |
