    copied!<p>This is a little embarrassing, but I have not been able to find good resources on this topic.</p> <p>I'm working on a Google App Engine application that requires sophisticated time zone conversions. Since I am nowhere near the imposed quotas, I have opted to go with PyTZ. However, I must be doing something wrong. What I've done so far is:</p> <ol> <li>Downloaded PyTZ as a tarball</li> <li>Installed it and copied the <code>pytz</code> directory into the root of my app (it is a sibling of the <code>webapp</code> directory, where <code>app.yaml</code> is located).</li> </ol> <p>However, if I try to instantiate timezones, PyTZ can never seem to find any. Here is a sample session from GAE's interactive console:</p> <pre><code>from pytz import timezone rome = timezone('Europe/Rome') </code></pre> <p>The output is the following:</p> <pre><code>Traceback (most recent call last): File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/ext/admin/__init__.py", line 210, in post exec(compiled_code, globals()) File "&lt;string&gt;", line 3, in &lt;module&gt; File "/Library/Python/2.5/site-packages/pytz-2009j-py2.5.egg/pytz/__init__.py", line 157, in timezone UnknownTimeZoneError: 'Europe/Rome' </code></pre> <p>What is it I am doing wrong? Thank you in advance for your help.</p> <p><strong>NOTE</strong>: If I just use the python interactive shell locally things work as expected:</p> <pre><code>&gt;&gt;&gt; from pytz import datetime, timezone &gt;&gt;&gt; rome = timezone('Europe/Rome') &gt;&gt;&gt; rome.localize(datetime.datetime.now()) datetime.datetime(2009, 11, 12, 0, 4, 52, 990114, tzinfo=&lt;DstTzInfo 'Europe/Rome' CET+1:00:00 STD&gt;) </code></pre> <p><em>Edit</em>: I need to clarify I'm not using a zipped version of PyTZ. I have included the whole <code>zoneinfo</code> directory in my project:</p> <pre><code>pc-morena:pytz lyudmilangelov$ cd zoneinfo/ pc-morena:zoneinfo lyudmilangelov$ ls -l total 448 drwxr-xr-x@ 55 lyudmilangelov staff 1870 Nov 10 12:48 Africa drwxr-xr-x@ 135 lyudmilangelov staff 4590 Nov 10 12:48 America drwxr-xr-x@ 12 lyudmilangelov staff 408 Nov 10 12:48 Antarctica drwxr-xr-x@ 3 lyudmilangelov staff 102 Nov 10 12:48 Arctic drwxr-xr-x@ 93 lyudmilangelov staff 3162 Nov 10 12:48 Asia ... </code></pre>
