for those who come here looking for the boot time, here is a program to convert the wmic format boot time to seconds then redisplay it. I cloned the HTTP::Date code then chopped it down to this. also being posted on http://www.perlmonks.org/?node_id=216892 

use strict;
use Time::Local;

sub wmic2time (;$)
{
    my $wmic_time_in=$_[0];
    if(!defined $wmic_time_in)
    {
        $wmic_time_in=join " ",`wmic os get lastbootuptime 2>&1`;
        $wmic_time_in=~s/\r\n/ /g;
        $wmic_time_in=~s/ * / /g;
    }
    $wmic_time_in=~s/LastBootUpTime //i;      # caller may have remove
+d this already but just in case....
    my @d = $wmic_time_in =~ /^(\d{4})(\d\d)(\d\d)(\d\d)(\d\d)(\d\d)/x
+;             # year numerical month day Hour Min Sec

    return undef unless @d;
    $d[1]--;        # month

    return eval { my $t = Time::Local::timelocal(reverse @d);
                  $t < 0 ? undef : $t;
                };
}

my $newtime=wmic2time;
print "$newtime\n";

print scalar localtime $newtime . "\n";
