A couple of things -
-
'u' in the pack template is UUEncoded text, I think you want 'U' for unicode, right? The template you are looking for should be "LU32PLU32PL"
-
Instead of " " x 32, pass a list of 32 32's, for example:
push @splist, 32 for (1 .. 32);
$tz_struct = pack("LU32PLU32PL", 0, @splist, $systime_struct,
0, @splist, $systime_struct, 0
+);
'P' and 'N' are constants defined in Win32::API, not strings. The third parameter to new Win32::API should be an anonymous list or an array reference, not a string literal
'GetTimeZoneInformation',
[P],
N
- Have fun unpacking the unicode string! If all you are interested in is the bias, try "LS64PLS64PL" for the template.
Update: Updated my Win32::API, and updated #3 above. Thanks mothra:-) BTW, $bias returns 480 after making the above modifications (UTC -8)

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.
