Display multiple timezone values from a single date/time entry
I guess that could be done using jQuery (or a separate module that does the same) but to me, the easiest way would be jQuery.
So you load your date/time field a second time in your view, &quot;Rewrite the output of this field&quot; so you can give it a different HTML structure and different classes name e.g.
&lt;div class=&quot;timezone2&quot;&gt;&lt;span class=&quot;gmt-label&quot;&gt;GMT &lt;/span&gt;&lt;span class=&quot;myOffsetTimezone&quot;&gt;+10:00&lt;/span&gt;&lt;div&gt;

Here's a link on how you could do that: getTimezoneOffset via javascript
The great thing with &quot;getTimezoneOffset&quot; is that it accounts for daylight savings time as well.
