I am trying to match the dot using the following regular expression 



#!/volume/perl/bin/perl
use warnings;
use strict;
use DateTime::Duration;

my $tim = "01:00:01.004";

$tim =~ s/:/./g;
print "new time is $tim";
my @outputlist = split /./, $tim;
print "$outputlist[0]\n";

[download]

It shows the following error . let me know how to split using dot

Use of uninitialized value in concatenation (.) or string at ./temp-ip2.pl line 11. new time is 01.00.01.004
