open my $fh, "<", $infile or die "error opening '$infile':$?";

The $? variable is not relevant in this context.    You should be using either $! or $^E.

if ( m/^(\d{2}:\d{2}:\d{2},\d+)\s\-\-\>\s(\d{2}:\d{2}:\d{2},\d+)/g + ) {

You are using the /g global option in a scalar context, which would make sense in a while loop, but the value of $_ changes each time you test it so it makes no sense to use it there.

my @elems = split(':', $time); my $seconds = pop @elems; my $minutes = pop @elems; my $hours = pop @elems;

Why not just:

my ( $hours, $minutes, $seconds ) = split /:/, $time;

# force to numerical $hours += 0; $minutes += 0; $seconds += 0;

An unnecessary step as the numbers are already numerical.

my $seconds = sprintf( "%02.3f", ( ( $sectime - ( $hours * 3600 ) +) - ( $minutes * 60 )) );

The number before the period in the format string for floating point is the total width.    So if you want the result to look like '12.345' then you need a format string of '%06.3f' because it has a total width of six characters.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
