Death of time

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;

END

my $now = &getime();

print<<END;
        It is curently $now
    </p>

END

###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() {

sub getime {

and fixed the month 'count-from-zero' bug.

Change `sub getime() {` to `sub getime {` to lose that particular error. Also note that the month returned is 0..11 -- so you might want to add one to it in getime. Edit: Forgot to mention: Be sure you know the difference between calling a sub via `&getime()` and `getime()`. You might want the latter form. See perlsub for more info.	[reply] [d/l] [select]

That has to do with @_ right? Partially. See this relevant bit from the perldoc: `NAME(LIST); # & is optional with parentheses. NAME LIST; # Parentheses optional if predeclared/imported. &NAME(LIST); # Circumvent prototypes. &NAME; # Makes current @_ visible to called subroutine.` [download] So the passing of @_ is affected, as is the prototyping. I'm not too familiar with prototypes in Perl, so I'm not sure how things are affected when prototypes are circumvented... which is why I pointed to the perldocs instead of spelling it out myself. I know there's a difference, but haven't really looked into it. ;)	[reply] [d/l]
