Here is the following from my console:>> Time.now=> Mon Sep 22 11:33:34 +0200 2008>> Time.now.utc_offset=> 7200>> TimeZone[Time.now.utc_offset]=> #<TimeZone:0x11aea90 @tzinfo=nil, @utc_offset=7200, @name="Athens">>> Time.now.in_time_zone(TimeZone[Time.now.utc_offset])=> Mon, 22 Sep 2008 12:34:22 EEST +03:00 (I am in Spain - CET - and running on OS X with the correct timezone) The Time.now correctly gives me the time, and the correct UTC offset of 2 hours. It is the summer, so we are 2 hours ahead of UTC. We are still one hour ahead of London, but London itself is an hour ahead as they too switch to a summer time (BST). ruby tells me that my utc_offset is 7200 - which is correct. But... when I pull out the timezone it gives me the wrong one. Athens is 3 hours ahead of UTC, not 2 (at this time of year). So, when I convert a time using the timezone it gives me it is an hour out! I had hoped that time zone woes were behind me after switching to RoR from Java. But it still seems to be a problem. How can I get the correct Time Zone? There is a bug tracked (http://dev.rubyonrails.org/ticket/4551) but it seems to be set to closed... but it definitely isn''t fixed! Right now I am doing this: offset = Time.now.dst? ? 60 : 0 Anyone have any better solutions? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Time.zone will give you the time zone currently set in Rails 2.1 You should set the time zone of your environment in the environment.db: config.time_zone = ''Amsterdam'' You can ask the users of your application to select their time zone (that''s something they''ll have to tell you, it''s not possible for Rails to guess :-)), save it in the user table as time_zone variable and set it for your current user in a before_filter: Time.zone @current_user.time_zone.

Hi, Thanks for that, but it completely misses the point in that I can not even get the proper time zone conversion inside the server. I am not bringing a user''s timezone into the equation! I can''t go back and forth inside the same instance and get reliable results: Time.now and Time.now.in_time_zone(TimeZone[Time.now.utc_offset]) should give me the same times back! it doesn''t. Anyway, I think I found another bug listed for this, so I will trust that someone more clever than I will figure it out.

Ok phil, I see the point you''re trying to make.
The thing I was trying to say is that it''s just not possible for Rails
to really know in which time zone you are. So when you call
TimeZone[some_offset], it can only make a guess about the time zone,
because it doesn''t know if you''re in a time zone with or
without DST.
Again, in Rails 2.1, you should set your time zone via the
config.time_zone command so that Rails knows in which time zone is
your server. And you retrieve your time zone (that was your question,
right?) using
Time.zone
So not using TimeZone.[] class method.
