Guys, I am a beginner in Perl, and I have a small query. I have written a script which selects a line from a file and extracts the date part of it. This date, I want to Parse (in anyway) to obtain the Epoch time. The error which I get and the code which I have written is as follows. I have tried a number of ways to parse the date. If I give ParseDate(""), it works, but if I give the line which I read from the file, it does not work. Please help. Error which I get: 
The 'year' parameter (undef) to DateTime::new was an 'undef', which is
+ not one of the allowed types: scalar
 at /usr/local/lib/perl/5.10.1/DateTime.pm line 200
    DateTime::new(undef, 'year', undef, 'month', 1, 'day', 1, 'hour', 
+1, ...) called at smsDone line 60

The Code which I have written 
$file_name = "sms.vmg";
tie my @array, 'Tie::File', $file_name or die("Unable to open file \"$
+file_name\": $!\n");

my $year = substr $array[13], 22, 8;
my $month = substr $array[13], 16, 2;
my $date = substr $array[13], 10, 4;
my $hour = substr $array[13], 32, 4;
my $minutes = substr $array[13], 38, 4;
my $seconds = substr $array[13], 44, 4;

$dt = DateTime->new(
year=>$year,
month=>$month,
day=>$date,
hour=>$hour,
minute=>$minutes,
second=>$seconds,
nanosecond=>0, time_zone => 'Asia/Calcutta');

$epoch_time  = $dt->epoch * 1000;
print "\nEpoch Time: ".$epoch_time;

Update: I missed adding ... the date is in the format "dd.mm.yyyy hh:mm:ss". For example "21.06.2010 07:06:11"
