Question

Javascript on my page saves client UTC offset to the cookie.
How do I use this cookie to create a TimeZone and assign it to Time.zone ?

I need something like:

before_filter :set_time_zone

def set_time_zone
  Time.zone = ActiveSupport::TimeZone.new('my timezone', cookies[:timezone])
end

except that the right part of this expression does not work and I’m not sure if I’m going the right way here. Can’t get it.

Answer 1

Here’s the working googled answer:

min = cookies[:timezone].to_i
Time.zone = ActiveSupport::TimeZone[-min.minutes]

Just to make it clear, the javascript part:

if(!($.cookie('timezone'))) {
  current_time = new Date();
  $.cookie('timezone', current_time.getTimezoneOffset(), { path: '/', expires: 10 } );
}
