Hello,

Per our forum rules, all threads must have a descriptive subject text. For example, do not post questions with subjects like "Help Me!", "Urgent!!" or "Doubt". Post subjects like "Execution Problems with Cron" or "Help with Backup Shell Script".

The reason for this is that nearly 95% of all visitors to this site come here because they are referred by a search engine. In order for future searches on your post (with answers) to work well, the subject field must be something useful and related to the problem!

In addition, current forum users who are kind enough to answer questions should be able to understand the essence of your query at first glance.

So, as a benefit and courtesy to current and future knowledge seekers, please be careful with your subject text. You might receive a forum infraction if you don't pay attention to this.

Thank you.

Are you passing one or two arguments to the script? You only mention YYYYMMDD but your code appears to be expecting two arguments:

Code:
my $d = $ARGV[0];
my $t = $ARGV[1];


Assuming two arguments, see if this helps:

Code:
use Time::Local;

my $d = $ARGV[0];
my $t = $ARGV[1];
my ($y, $m, $d) = unpack("A4A2A2",$d)
my ($h, $min, $s) = split(/:/,$t);
$time = timelocal($s, $min, $h, $d, $m-1, $y);

print "$time\n";usage :

That's because the line does not end properly, thereby forcing the perl interpreter to baulk.
