Thanks. Yes, that example is OO. Here it is reworked non-OO:

my @opts= qw( second minute hour day month year
    weekday yearday isdst );
my %opts;
@opts{@opts}= 0..$#opts;

sub LocalTime
{
    my $time= shift(@_);
    my @values= localtime($time);
    return @values   if  ! @_;   # Optional but may save CPU (:
    my $href= {};
    $href= shift(@_)   if  @_  &&  UNIVERSAL::isa($_[0],"HASH");
    @_= @opts   if  ! @_;
    foreach my $opt (  @_  ) {
        croak "LocalTime:  Invalid option ($opt) not one of ",
            "( @opts )"   unless  defined $opts{$opt};
        $href->{$opt}= $values[$opts{$opt}];
    }
    return @{$href}{@_};
}

Note that these versions let you do interesting things like:

my $year= LocalTime( time(), \(my %time),
    qw( second minute hour day month year ) );
