DateTime is a date and time object.

SYNOPSIS

use DateTime;

$dt = DateTime->new( year => 1964,
month => 10,
day => 16,
hour => 16,
minute => 12,
second => 47,
nanosecond => 500000000,
time_zone => Asia/Taipei,
);

$dt = DateTime->from_epoch( epoch => $epoch );
$dt = DateTime->now; # same as ( epoch => time() )

$year = $dt->year;
$month = $dt->month; # 1-12 - also mon

$day = $dt->day; # 1-31 - also day_of_month, mday

$dow = $dt->day_of_week; # 1-7 (Monday is 1) - also dow, wday

$hour = $dt->hour; # 0-23
$minute = $dt->minute; # 0-59 - also min

$second = $dt->second; # 0-61 (leap seconds!) - also sec

$doy = $dt->day_of_year; # 1-366 (leap years) - also doy

$doq = $dt->day_of_quarter; # 1.. - also doq

$qtr = $dt->quarter; # 1-4

# all of the start-at-1 methods above have correponding start-at-0
# methods, such as $dt->day_of_month_0, $dt->month_0 and so on

$ymd = $dt->ymd; # 2002-12-06
$ymd = $dt->ymd(/); # 2002/12/06 - also date

$mdy = $dt->mdy; # 12-06-2002
$mdy = $dt->mdy(/); # 12/06/2002

$dmy = $dt->dmy; # 06-12-2002
$dmy = $dt->dmy(/); # 06/12/2002

$hms = $dt->hms; # 14:02:29
$hms = $dt->hms(!); # 14!02!29 - also time

$is_leap = $dt->is_leap_year;

# these are localizable, see Locales section
$month_name = $dt->month_name; # January, February, ...
$month_abbr = $dt->month_abbr; # Jan, Feb, ...
$day_name = $dt->day_name; # Monday, Tuesday, ...
$day_abbr = $dt->day_abbr; # Mon, Tue, ...

$epoch_time = $dt->epoch;
# may return undef if the datetime is outside the range that is
# representable by your OSs epoch system.

$dt2 = $dt + $duration_object;

$dt3 = $dt - $duration_object;

$duration_object = $dt - $dt2;

$dt->set( year => 1882 );

$dt->set_time_zone( America/Chicago );

$dt->set_formatter( $formatter );

DateTime is a class for the representation of date/time combinations, and is part of the Perl DateTime project. For details on this project please see http://datetime.perl.org/. The DateTime site has a FAQ which may help answer many "how do I do X?" questions. The FAQ is at http://datetime.perl.org/faq.html.

It represents the Gregorian calendar, extended backwards in time before its creation (in 1582). This is sometimes known as the "proleptic Gregorian calendar". In this calendar, the first day of the calendar (the epoch), is the first day of year 1, which corresponds to the date which was (incorrectly) believed to be the birth of Jesus Christ.

The calendar represented does have a year 0, and in that way differs from how dates are often written using "BCE/CE" or "BC/AD".

For infinite datetimes, please see the DateTime::Infinite module.

Rose::DateTime is a Perl module with DateTime helper functions and objects.

SYNOPSIS

use Rose::DateTime::Util qw(:all);

$now = parse_date(now);
$then = parse_date(12/25/2001 6pm);

$date_text = format_date($then, "%D at %T %p");

...

use Rose::DateTime::Parser;

$parser = Rose::DateTime::Parser->new(time_zone => UTC);

$date = $parser->parse_date(12/25/1999);

The Rose::DateTime::* modules provide a few convenience functions and objects for use with DateTime dates.

Rose::DateTime::Util contains a simple date parser and a slightly customized date formatter.

Rose::DateTime::Parser encapsulates a date parser with an associated default time zone.

This module (Rose::DateTime) exists mostly to provide a version number for CPAN. See the individual modules for some actual documentation.

Perl Chat is a project that consists of a client and a server, both written in perl.

The goal of this project is to create a chat server that can be used on smaller networks such as a college campus or a business network.

Both the client and the server are written in Perl, and the client uses the Tk module to generate its GUI.

Installation:

First of all you need a working version of Perl. Preferably 5.6 but 5.005X should also work fine. For versions of Perl Chat < 0.1.0 you will need to compile Perl with Threads. (Keep in mind that Threads are still experimental) I designed this program with Perl 5.6.0 which can be found HERE.

You will need to read the installation instructions to compile it with Threads. I advise anyone who is doing this to install this new version of perl into /usr/local/ so as to not overwrite your old perl. Then by changing the first line of the script you can toggle between the different installs of perl.

Lingua::ZH::DateTime is a Perl module to convert time to chinese format.

SYNOPSIS

This module can convert asctime to chinese format in your locale. you can select china singapore hongkong taiwan locale and gb2312/big5 charset. asctime is ASC C standard format will from localtime like this:

$asctime = localtime();

DateTime::Locale is a Perl module with localization support for DateTime.pm.

SYNOPSIS

use DateTime::Locale;

my $loc = DateTime::Locale->load(en_GB);

print $loc->native_locale_name, "n",
$loc->long_datetime_format, "n";

# but mostly just things like ...

my $dt = DateTime->now( locale => fr );
print "Aujourdhui le mois est " . $dt->month_name, "n":

DateTime::Locale is primarily a factory for the various locale subclasses. It also provides some functions for getting information on available locales.

If you want to know what methods are available for locale objects, then please read the DateTime::Locale::Base documentation.

Rose::DateTime::Util Perl module contains some simple DateTime wrapper functions.

SYNOPSIS

use Rose::DateTime::Util qw(:all);

$now = parse_date(now);
$then = parse_date(12/25/2001 11pm);

print $now->day_of_week; # e.g., "Monday"

# "December 25th 2001 at 11:00:00 PM"
$date_text = format_date($then, "%B %E %Y at %t");

EXPORTS

Rose::DateTime::Util does not export any function names by default.

The all tag:

use Rose::DateTime::Util qw(:all);

will cause the following function names to be imported:

format_date()
parse_date()
parse_epoch()
parse_european_date()

CLASS METHODS

error

Returns a message describing the last error that occurred.

european_dates [BOOL]

Get or set a boolean flag that determines how "xx/xx/xxxx" dates are parsed by the parse_date function. If set to a false-but-defined value, then such dates are parsed as "mm/dd/yyyy". If set to true, then theyre parsed as "dd/mm/yyyy". If set to undef, then the attribute resets to its initial value, which is determined as described below.

The initial value of this attribute is chosen based on the current locale as stored in DateTimes DefaultLocale setting. This initial value is looked up only once. Any subsequent changes to DateTimes DefaultLocale setting will be ignored until/unless this attribute is reset to undef.

time_zone [TZ]

Get or set the default time zone. This value is passed to DateTime->new(...) as the value of the time_zone parameter when parse_date() creates the DateTime object that it returns. The default value is "floating".

Perl OS is a program written in the Perl programming language combined with the Perl module Tk.

Perl OS was created to make an easy interface to run Perl/Tk programs. It was also created to be an easy working environment complete with a text editor, paint program, and more.

The program comes with several programs, along with a utility to add many more which can be found on the Internet.

From the outside, Perl OS looks like a simple operating system. But inside, it is a powerful system for working with Perl and Tk.

For more details please visit the Perl OS home page:

Davids Perl Games project is a collection of ASCII graphics arcade style games written in Perl.

These games are recreations of simple ASCII graphics games originally written in BASIC.

They are ideal for use as Perl programming tutorials. Some of the first few games are PerlBlaster (defend your planet from invading aliens), PerlRacer (steer your car through the twisting passages), and PerlArena (eliminate the mutant hordes).
