Yes I really know this isn't much of a CUFP, since it's been done many times before, but just change 
$date2
and you have a handy countdown to any time you want! 
#!/usr/bin/perl

###Load Modules
use warnings;
use strict;
use Date::Manip;
use Time::HiRes;
use CGI;
my $cgi = new CGI;

###Set $err so you can specify a mode for &DateCalc
my $err;

###Set Dates to Calculate for, then Find Difference
my $curtime = getime();
my $date1 = &ParseDate($curtime);
my $date2 = &ParseDate("03:14:06 Jan 19 2038");
my $delta = &DateCalc($date1,$date2,\$err,1);

###Populate Data hash
my %data;
@data{qw/years months weeks days hours minutes seconds/} = $delta =~ /
+(\d+)/g;

###Begin HTML Output, yes this is bad, but it's quick-n-dirty :)
print $cgi->header();

print<<END;

my $now = &getime();

###Get current time (GMT)
sub getime() {
    my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = gmtime(
+);
    ###Correct for 'zero math'
    $year += 1900;
    $mon += 1;
    my $time =  "$hour:$min:$sec $mon\/$mday\/$year";
    return $time;
}

Yes I know it's not the best script around, or best written, but I like it

Edit: Changed 

sub getime() {
to 
sub getime {
and fixed the month 'count-from-zero' bug.
