Hello Monks,

I was wondering if one method is 'better' then the other...?

I'm using the Date and Time values quite a few times in my script to calculate what is basically a 'start' and
'end' times to be used within another script. Which can be present and/or future date and times...

So is one of these 2 methods below better to use, for any reason, then the other one?
#!/usr/bin/perl

use strict;
use warnings;
use DateTime;

### Method one... Using the DateTime Function:
my $date = DateTime->now->set_time_zone('America/New_York');

    # Get the individual values of each below:
    my $month = $date->month();
    my $day = $date->day();
    my $year = $date->year();
    my $min = $date->minute;
    my $hour = $date->hour;
    my $sec = $date->second;

    print "\tMonth --> $month\n";
    print "\t  Day --> $day\n";
    print "\t Year --> $year\n";
    print "\t Hour --> $hour\n";
    print "\t  Min --> $min\n";
    print "\t  Sec --> $sec\n";

    print "\t\n$month/$day/$year $hour:$min:$sec\n\n";

print "####################################\n\n";

### Method 2: Use the localtime(time) Function:
my ($sec1,$min1,$hour1,$day1,$month1,$year1,@rest) = localtime(time);
    $month1 += 1;        # Add one to Month to get actual
    $year1 += 1900;        # Add 1900 to year to get actual

    print "\tMonth --> $month1\n";
    print "\t  Day --> $day1\n";
    print "\t Year --> $year1\n";
    print "\t Hour --> $hour1\n";
    print "\t  Min --> $min1\n";
    print "\t  Sec --> $sec1\n";

    print "\t\n$month1/$day1/$year1 $hour1:$min1:$sec1\n\n";

***************** END SCRIPT *****************

Each of those produces pretty much the same result except the Month is Zero-based and the year is
the number of years since 1900 (*i.e. this year == 113, get actual year by "$year += 1900")...

I'm using each piece of the Date and Time variables at some point later on in the script. So I do need
each individual piece of the date and Time vars cause I use them quite a few times in the script.

Any thoughts or suggestions would be much appreciated.

Thanks in Advance,
Matt
