Thanks for this illustration. I have some small suggestions, however.
- There is no need to "use" a module multiple times within the same scope.
- When you have imported a symbol into the current namespace there is no need to use the package name to refer to it.
- There is no need to declare variables which are not used ($wday, $yday, $isdst). If the others aren't used beyond the print statement, we don't need those either.
- print print is rather pointless since the first print just outputs the return value of the second.
Cleaning this up gives us:
use POSIX 'strftime';
print strftime ('%I:%M:%S %p - %a, %B %d, %Y', localtime (time)) . "\n
+";
I prefer the brevity of this and think it aids clarity. However, here's the same but with 2 named variables just for completeness:
use POSIX 'strftime';
my $format = '%I:%M:%S %p - %a, %B %d, %Y' . "\n";
my @time = localtime (time);
print strftime ($format, @time);

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).
