My first Perl module doesn't work

I want to test my first Perl module and need some help.
I have a module:
  package Util;
  require Exporter;
  our @ISA        = qw(Exporter);
  #our @Export     = qw(timestamp);
  our @Export_OK  = qw( &timestamp );
  our $VERSION    = 1.00;
sub timestamp {...}

The Perl program:
 use Utils qw( timestamp );
 my $x2 = timestamp();

 The error is:
Undefined subroutine &main::timestamp called at K:\SOURCE\Perl\Utils\Test.pl line 8.
Changing to my $x2 = Utils::timestamp():
Undefined subroutine &Utils::timestamp called at K:\SOURCE\Perl\Utils\Test.pl line 8.

The program is at x:\perl\src
The module is at y:\perl\_mymodules
Perl install is on e:\perl
Perl is ActiveState

Anybody an idea how to resolve the problem?
I wouldn't like to install the module while testing it.
(but nethertheless: Howto do that?)

BTW: @INC has added the path to the module dir. Also the PERL5LIB environment var.

Thats it.

Ashes on my head.

Maybe you could give me a hint to the then following problem:
use Utils qw( timestamp ); # shows following error:
cant continue after import errors BEGIN failed

Got it all.
@Export     = qw(timestamp);
@Export_OK  = qw( &timestamp );
Export.. has all to be uppercase.

That resolved the err:
  cant continue after import errors BEGIN failed

Thanks folks.

your utils module misses to return "true", add a final line:

1;

To ahoffman:
the "1;" is there.
I published only the short form with in my eyes relevant parts.

But as I said: Anything works fine now.
Thank You!
