Hello! I am new to perl. And now I need monks' help with a problem related to hash.

I am trying to merge two hashes. I have fields of time, conference, type, comment. I have no problem with time as hash key.

while (<FILE>)
{
my %hash = ();
$hash{$time}{'conference'} = $value1;
$hash{$ime}{'type'} = $value2;
$hash{$time}{'comment'} = $value3;
}

for my $time (sort keys %hash)
{
print .... #element
}

But how do I do the same thing (add element and access later) if I use time and conference as multi value key in the hash. I could add time and conference to the key using push, but how to refer to it to add $type, $comment and later to print all four fields?

Thanks for help!
