localtime - make the date format different?

ultranerds has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I'm trying to make this code:

    my @stats = stat("$folder/$file");
    my $date = localtime $stats[9];
[download]

..so that instead of showing something like:

Tue Aug 16 19:23:30 2005

..I want more like:

2008-10-15 12:43:00

Is this even possible?

TIA!

Andy
