There is not much more to show. Most is boring data manipulation that leads to the final array. The array holds only numbers. Nothing embedded. 

my $conn = MongoDB::Connection->new;
my $db = $conn->mydb || die "$!";
my ($col, $cols, @cols, $q, $doc, @b, @c, @new, $x, $date, $l, $host);
+ 

@cols = $db->collection_names;

foreach $cols (@cols) {

Above a loop through some collections and for each make the new array. Then I try to replace the array. 

if ( @new > 1 ){

        foreach my $xxx (@new){ print '@new = '.strftime('%Y-%m-%d', l
+ocaltime($xxx))."\n"; }
      $col->update( 
                 { "host" => $host },
                 {
                            '$set' => {  "timestamp" => @new }
                 },
                 { 'multiple' => 1, 'safe' => 1 }
      ) || die "$!";

The foreach loop above is just to show there is data in @new. That works :). The update fails. The documentation for MongoDB is a bit sparse. I assume my syntax is wrong. Alas, I cannot figure how.
