Hi,

I am using the tzinfo gem and plugins to manage time zone support in my  
app.

In one of the views I have the following select  
\<%= time\_zone\_select ‘user’, ‘time\_zone’, TZInfo::Timezone.all.sort,  
:model =\> TZInfo::Timezone %\>

This produces a list of all possible countries, does anyone know of a  
way to only display the UTC + / - options and not the named places?

thanks

I’m not familiar with the tzinfo gem but you should be able to use  
something like this:

TZInfo::Timezone.all.sort.collect { |tz| [tz.name] }
