📝 NAME

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

🚀 Quick Reference

Use Case	Command	Description
Get gmtime object	use Time::gmtime; $gm = gmtime();	Use object interface with methods like sec, min, hour, etc.
Import fields directly	use Time::gmtime qw(:FIELDS); gmtime();	Access $tm_sec, $tm_mday, etc. as plain variables.
Get scalar gmtime string	$now = gmctime();	Returns standard GMT string (like CORE::gmtime in scalar context).
Use with File::stat	gmctime(stat($file)->mtime)	Convert file modification time to GMT string.
Access core gmtime without override	use Time::gmtime (); CORE::gmtime()	Use empty import list to avoid function override.

📋 SYNOPSIS

     use Time::gmtime;
     $gm = gmtime();
     printf "The day in Greenwich is %s\n",
        (qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ $gm->wday() ];

     use Time::gmtime qw(:FIELDS);
     gmtime();
     printf "The day in Greenwich is %s\n",
        (qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ $tm_wday ];

     $now = gmctime();

     use Time::gmtime;
     use File::stat;
     $date_string = gmctime(stat($file)->mtime);

📖 DESCRIPTION

This module's default exports override the core gmtime() function, replacing it with a version that returns Time::tm objects. This object has methods that return the similarly named structure field name from the C's tm structure from time.h; namely sec, min, hour, mday, mon, year, wday, yday, and isdst.

You may also import all the structure fields directly into your namespace as regular variables using the :FIELDS import tag. (Note that this still overrides your core functions.) Access these fields as variables named with a preceding tm_ in front their method names. Thus, $tm_obj->mday() corresponds to $tm_mday if you import the fields.

The gmctime() function provides a way of getting at the scalar sense of the original CORE::gmtime() function.

To access this functionality without the core overrides, pass the 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 CORE:: pseudo-package.

⚠️ NOTE

While this class is currently implemented using the Class::Struct module to build a struct-like class, you shouldn't rely upon this.
