time_select(object_name, method, options = {}) public

Returns a set of select tags (one for hour, minute and optionally second) pre-selected for accessing a specified time-based attribute (identified by method) on an object assigned to the template (identified by object). You can include the seconds with :include_seconds. Examples: 

  time_select("post", "sunrise")
  time_select("post", "start_time", :include_seconds => true)

The selects are prepared for multi-parameter assignment to an Active Record object.

2.1 sets UTC time by default

Rails 2.1 sets hour select to UTC time value, not local server time by default. So if you’re not in UTC time zone don’t forget to specify timezone in your config/environment.rb: config.time_zone = 'Vilnius'

Set time zone in before filter

To set your time zone you could create a before_filter in your application.rb controller 

 class ApplicationController < ActionController::Base

  before_filter :set_timezone

  def set_timezone
    Time.zone = 'GMT'
  end

 end
