Hello jnarayan81,

The monks have already provided you with wisdom, but I am wondering why don't you simply call it through a subroutine. Your script works just fine as soon as you call the subroutine every instance that you want it.

Sample:

#!usr/bin/perl
use say;
use strict;
use warnings;
use POSIX q(strftime);

my @abc = ("a", "b", "c", "d", "e");

sub fetchTime {
    return POSIX::strftime('%a, %d %b %Y %T %z', localtime);
}

for (@abc) {say fetchTime() . "\t$_"; sleep 1;}

__END__

$ perl time.pl
