here's a version that doesn't rely on parsing the output of the scalar version of localtime: 
#!/usr/bin/perl -w

use strict;
use Net::Time qw(inet_time);

my $date_and_time = inet_time('cesium.clock.org', 'tcp');

my ($sec, $min, $hour, $day, $month, $year) =
    (localtime($date_and_time))[0..5];

my $new_date = sprintf "%02d/%02d/%04d", $month + 1, $day, $year + 190
+0;
my $new_time = sprintf "%02d:%02d:%02d", $hour, $min, $sec;

system('time', $new_time) or die "Couldn't set time: $!";
system('date', $new_date) or die "Couldn't set date: $!";
