# Time::gmtime(3pm)

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

## NAME

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

## 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 w(:FIELDS;
 printf "The day in Greenwich is %s\n",
    (qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ gm_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()* funtion 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.
