<p><b>New page</b></p><div>== DateTime won't build ==<br />
<br />
* In building DateTime on some computers you may need to install [http://search.cpan.org/~kwilliams/Module-Build/ Module::Build] first.<br />
* In some cases installations have had to reset the environment variable =LANG= in order to get Module::Build to compile. Use <code>export LANG=C</code> (sh/bash) or <code>setenv LANG C</code> (csh/tcsh).<br />
<br />
== When printing hardcopy with the "Show Correct Answers" option enabled, users get an error message similar to HASH(0x18fa4348) in the subroutine DateTime::TimeZone::new ==<br />
<br />
DateTime tries to calculate the time zone in various ways from data available on the server. These methods can fail and cause seemingly-unrelated errors, for example in [http://webhost.math.rochester.edu/webworkdocs/discuss/msgReader$3815?mode=topic&y=2006&m=7&d=20) printing hardcopy].<br />
<br />
To work around this, set the variable <code>$siteDefaults{timezone}</code> in <code>global.conf</code> to a valid time zone. For example:<br />
<br />
$siteDefaults{timezone} = "America/New_York";<br />
<br />
Further information is available in <code>global.conf</code>. Search for <code>timezones</code>. <code>globalconf</code> also contains instructions for finding the appropriate name for your local time zone. The command to list all time zone names is:<br />
<br />
perl -MDateTime::TimeZone -e 'print join "\n", DateTime::TimeZone::all_names';</div>
