I have a .csv file I'm parsing through, making several changes including reformatting the dates for the .csv file to be used by a MySQL program later. I'm not having a problem formatting DATE, but am not getting a response formatting DATETIME. Here is the section of code I'm running while reading through each line 
while($line = <$FH>) {

# split the fields, concatenate the first three fields,
# and add it to the beginning of each line in the file
    chomp($line);
    my @fields = split(/,/, $line);
    unshift @fields, join '_', @fields[0..2];
    $_ = join '-', (split /\//)[2,0,1] for $fields[14];
    $_ = join '-', (split /\//)[2,0,1] for $fields[20];
    $_ = join '-', (split /\//)[2,0,1] for $fields[23];
    $_ = Time::Piece->strptime($fields[38],'%m/%d/%Y %H:%M')->strftime
+('%Y-%m-%d %H:%M');
    $_ = Time::Piece->strptime($fields[39],'%m/%d/%Y %H:%M')->strftime
+('%Y-%m-%d %H:%M');
    push @data, \@fields;
}

The Time::Piece lines are not working. I'm not getting any errors, but they are not changing the Date within the DATETIME variable for each record from MM/DD/YYYY 00:00 to YYYY-MM-DD 00:00 as I need. What am I missing here?

Update

I have found the correct way to this - updated below 
while($line = <$FH>) {

# split the fields, concatenate the first three fields,
# and add it to the beginning of each line in the file
    chomp($line);
    my @fields = split(/,/, $line);
    unshift @fields, join '_', @fields[0..2];
    $_ = join '-', (split /\//)[2,0,1] for $fields[14,20,23];
    $_ = Time::Piece->strptime($_,'%m/%d/%Y %H:%M')->strftime('%Y-%m-%
+d %H:%M') for @fields[38,39];
    push @data, \@fields;
}

Now I've run into another problem for which I'll have to open a separate question!
