NAME ^

DateStamp - A simple OO interface to current system time and date.

VERSION ^

This document describes DateStamp version 1.0.4

SYNOPSIS ^

    use DateStamp;
    my $date_obj = DateStamp->new();
    my $year = $date_obj->return_year(length=>'long'); # $year = 2005
    my $day  = $date_obj->return_day(format=>'numeric');# day = 27
    my $time = $date_obj->return_time(format=>'12', length=>'short'); # $time = 5:12 p.m.
    my $date = $date_obj->return_date(format=>'yyyymmdd'); # $date = 20051127

DESCRIPTION ^

This module provides a simple OO interface to current system time and date information. The module provides not only access to individual components of localtime, but also several frequently used date format combinations (e.g., localtime, yyyymmdd, mm-dd-yyyy, month-day-year). See return_date under INTERFACE section for full list of date formats.

INTERFACE ^

The following methods are supported:

new

new: Class constructor; no arguments are sent to this method. The new method must be called everytime a snapshot of the current system time/date is desired.

 my $date_obj = DateStamp->new();

return_year

return_year: This method will return the numeric value of the current year. Two possible return formats are available: short & long.

 $date_obj->return_year(length=>'short');  # 05
 $date_obj->return_year(length=>'long');   # 2005

return_month

return_month: This method will return either an alpha or numeric value for the current month in a variety of formats.

 $date_obj->return_month(format=>'alpha', length=>'short');  # Nov 
 $date_obj->return_month(format=>'alpha', length=>'long');   # November
 $date_obj->return_month(format=>'numeric');                 # 11

return_day

return_day: This method will return either an alpha or numeric value for the current day in a variety of formats.

 $date_obj->return_day(format=>'alpha', length=>'short');  # Sun
 $date_obj->return_day(format=>'alpha', length=>'long');   # Sunday
 $date_obj->return_day(format=>'numeric');                 # 27

return_time

return_time: This method will return a variety of time formats. The time in this sense is literally a "timestamp", in that it captures the time at the moment the date object is created--and *not* when the method is called.

 $date_obj->return_time(format=>'12', length=>'short');  # 12:56 a.m.
 $date_obj->return_time(format=>'12', length=>'long' );  # 12:56:32 a.m.
 $date_obj->return_time(format=>'24', length=>'short');  # 00:56
 $date_obj->return_time(format=>'24', length=>'long' );  # 00:56:32
 $date_obj->return_time(format=>'localtime'          );  # Sun Nov 27 00:13:56 2005 

return_date

return_date: This method provides serveral frequently used, pre-compiled date combinations. The combinations are not meant to be exhaustive, as other combinations can be arrived at by combining the aforementioned month/day/year/timestamp methods. Both the "yyyymmdd" & "mmddyyyy" formats accept a "glue" argument, placing a provided symbol between month, day, and year.

 $date_obj->return_date(format=>'yyyymmdd');                # 20051127 
 $date_obj->return_date(format=>'yyyymmdd', glue=>'-');     # 2005-11-27 
 $date_obj->return_date(format=>'mmddyyyy');                # 11272005
 $date_obj->return_date(format=>'mmddyyyy', glue=>'/');     # 11/27/2005
 $date_obj->return_date(format=>'month-day-year');          # November 27, 2005
 $date_obj->return_date(format=>'mon-day-year');            # Nov 27, 2005 
 $date_obj->return_date(format=>'weekday-month-day-year');  # Monday, November 27, 2005
 $date_obj->return_date(format=>'month-day');               # November 27
 $date_obj->return_date(format=>'mon-day');                 # Nov 27

DIAGNOSTICS ^

A user may encounter error messages associated with this module if required method arguments are malformed or missing.

DateStamp reports: Bad/missing "format" argument.

[A user has invoked a method that requires a "format" argument of type valid for the method called. Check spelling, case (lower-case required), and argument types associated with the method in question.]

DateStamp reports: Bad/missing "length" argument.

[A user has invoked a method that requires a "length" argument of type valid for the method called. Check spelling, case (lower-case required), and argument types associated with the method in question.]

ACKNOWLEDGMENTS ^

Yup, this is my first CPAN module; I wanted to contribute something very simple to start with. Thanks to Andy Lester for his presentation "The A-Z Guide To Becoming a CPAN Author" at the St. Louis Perl Monger chapter meeting in November, 2005. His insight helped greatly in illuminating some dark areas of my skill-set. Andy's talk also galvanized me to finally contribute something to CPAN after 8 years of perl programming.
