&gt; We have received a report that the Solomon Island timezone is being<br>
&gt; calculated as if daylight savings was observed there, but it is in fact not<br>
&gt; the case.<br>
&gt;<br>
&gt; - Using tzinfo (0.3.31)<br>
&gt; - &quot;Pacific - Guadalcanal&quot;<br>
&gt; - ActiveSupport::TimeZone.all returns: &quot;(GMT+12:00) Solomon Is.&quot;<br>
&gt;<br>
&gt; But Solomon Island should be GMT+11<br>

<br>
</div>TZInfo does return an offset of GMT+11 for the Solomon Islands<br>
(Pacific/Guadalcanal) and indicates that daylight savings is not<br>
observed:<br>
<br>
&gt; zone = TZInfo::Timezone.get(&#39;Pacific/Guadalcanal&#39;)<br>
&gt; period = zone.period_for_utc(Time.utc(2013, 1, 1))<br>
&gt; period.utc_total_offset / 3600.0<br>
=&gt; 11.0<br>
&gt; period.dst?<br>
=&gt; false<br>
<br>
ActiveSupport::TimeZone maps &quot;Solomon Is.&quot; to the Asia/Magadan<br>
timezone (in the MAPPING Hash in<br>
lib/active_support/values/time_zone.rb). Since Magadan is a town in<br>
Russia that observes a timezone of GMT+12, the ActiveSupport mapping<br>
would appear to be incorrect.<br>
<br>
Kind regards,<br>
