I'd just use Time::HiRes' method tv_interval:
use Time::HiRes qw(gettimeofday tv_interval);
my $TH = [gettimeofday];
sub report {
print $_[0],': ',tv_interval($TH),"\n";
$TH = [gettimeofday];
}
A: {
...do things...
}
report("A");
B: {
...do some other stuff...
}
report("B");
C: {
...why not more stuff here...
...and some more!...
}
report("C");
<update>
...and to generate sums of the the times elapsed between checkpoints
my %TH;
sub report {
$TH{$_[0]} += tv_interval($TH);
$TH = [gettimeofday];
}
...
print "$_: $TH{$_}\n" for keys %TH;
</update>
--shmem

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).

or How to display code and escape characters
are good places to start.
