Moderator's Comments:
Please use code tags for listings and console output.
If you just need last shutdown; try using the command:
Code:
uptime
you can do some calculation with curent date-time to get the exact shutdown date.
Note: There might be few hours difference; as shutdown time and uptime would not be same; this difference of hours would be system downtime.
This may result in date change also, if shutdown occured around midnight or system downtime was fairly large.
Hope this helps.

Reason: spell error
Have a look at the "fwtmp" command. This can be used to read the file which "last" uses and outputs the history in text format - including the full date.
You can use awk, sed, perl, and numerous other tools to extract and format the date and time of the last reboot to your liking. Please note that the year is not displayed.
You can parse /var/log/wtmp to get what you need. For instance, using the examples in Formatting and Printing Wtmp as a starting point:
Code:
#! /usr/bin/perl
use strict;
use warnings;
use POSIX qw{ strftime };
undef $/;
$\ = "\n";
$, = '';
my $reclen = 384; # sizeof (struct utmp)
my $linesize = 32; # value of UT_LINESIZE in /usr/include/bits/utmp.h
my $namesize = 32; # value of UT_NAMESIZE in /usr/include/bits/utmp.h
my $hostsize = 256; # value of UT_HOSTSIZE in /usr/include/bits/utmp.h
my $wtmpfile = '/var/log/wtmp';
my $entry_template = "(a$reclen)*";
my $utmp_template = "I x4 x$linesize x4 x$namesize x$hostsize x4 x4 I";
my @UT_TYPE = qw{ Empty RunLvl Boot NewTime OldTime Init Login Normal Term Account };
open FH, '<', $wtmpfile or die $wtmpfile;
my $boot = undef;
foreach my $entry (unpack $entry_template, <FH>) {
my ($type, $when) = unpack $utmp_template, $entry;
$boot = $when if $UT_TYPE[$type] eq 'Boot';
}
close FH;
print strftime '%Y-%m-%d %H:%M:%S %Z', localtime $boot if defined $boot;
