print "module( ... ... $display("The time is %d",$time)\n";
      ^_OPEN                    ^_CLOSE       ^_OPEN     ^_CLOSE

Shortest way to fix it is with alternate delimiter ({} needs to be balanced)

print qq{module( ... ... $display("The time is %d",$time)\n};

interpolation, read about it in perlintro, perlop, and Modern Perl, search for "interpolat", in short, single quotes do not interpolate, http://perldoc.perl.org/perltrap.html#Interpolation-Traps and http://perldoc.perl.org/perlop.html#Quote-and-Quote-like-Operators

Rather than your vague problem description, in future please provide a precise, specific code snippet (embedded in <CODE>...</CODE> tags) of what is not working for you.

An example of such a specific code snippet is:

use strict;
use warnings;
print "module( ... ... \$display(\"The time is %d\",\$time)\n";

module( ... ... $display("The time is %d",$time)
