Hi all, I know this is very basic question, but I am loosing my mind trying to solve it. Task is very simple, I am trying to create simple application to read data from serial port. The problem I have is Tk. I created nice window but I can not find out how to update textvariable for particular labels. Here is a simple example of code that should display current Unixtime, but does not, what is the problem?? 
#!/usr/bin/perl 
use warnings;
use strict;

use Tk;



my $mw =  new MainWindow;
my $label = $mw -> Label(-textvariable =>\&timer);
$label -> grid(-row=>1,-column=>1);

$mw->repeat(1000,\&timer);


MainLoop;

sub timer{
    my $time = time();
}
