Sure, but first you have to write valid perl

$ cat EchoStartStop.pm;

package EchoStartStop;
use POSIX();
BEGIN {
    print "Started: ",POSIX::strftime( "%a %b %d %T %Z %Y", localtime 
+),"\n";

}
END {
    print "Stopped: ",POSIX::strftime( "%a %b %d %T %Z %Y", localtime 
+),"\n";

}

It might suit your needs to simply

$ perl -le"print scalar localtime"
