Setting Fixed Time Zone (without time savings)
FF
Ruby 1.8.6
Rails 2.3.2
Environment.rb
config.time_zone = 'Buenos Aires'
This zone is usually GMT -3:00hs but in this moment os the year it
gives GMT -2.00 hs because the world time saving
conventions....but...our country (Argentina) don't adopt the time
saving convention this year...
How can I set the time zone to get an fixed GMT -3.00 ?
Thanks

Update/Patch your OS, seriously. First example below is on a newly installed
OpenSuSE 11.2. Or second method below (per http://rails.rubyonrails.org/).
Both are UTC -03:00. You indicate that your computer is giving you Buenos
Aires is UTC -02:00. If the OS has been patched recently, try restarting the
Rails server to get the new TZ info.
>> tz = ActiveSupport::TimeZone["Buenos Aires"]
=> #<ActiveSupport::TimeZone:0xb6e9670c @tzinfo=nil, @utc_offset=-10800, @name="Buenos Aires">
>> tz = ActiveSupport::TimeZone[-3]
=> #<ActiveSupport::TimeZone:0xb6e966f8 @tzinfo=nil, @utc_offset=-10800, @name="Brasilia">
HTH,

My OS is WindowsXP SP3. The time saving is running ok for all the apps
in the computer.
So my computer is giving me, UTC -03:00.
Rails with the time_zone set to "Buenos Aires"...gives -02:00 so the
problem is only with Rails.

Which version of ActiveSupport do you have? I had assumed that TZ info was
coming from the OS, but digging into the Rails libraries, that turns out not
to be true. Shame on me. The information is in:
activesupport-2.x.y/lib/active_support/vendor/tzinfo-0.3.12/tzinfo/definitions/America/Argentina/Buenos_Aires.rb
Note: if the version of tzinfo is different, this probably is where your
problem is. I checked ActiveSupport 2.3.3 and 2.3.5 and they are the same.

My Path is:
activesupport-2.3.2/lib/active_support/vendor/tzinfo-0.3.12/tzinfo/
definitions/America/Argentina/Buenos_Aires.rb
I edited the file and commented this two lines I think may sense.
# tz.transition 2009, 10, :o5, 1255834800
# tz.transition 2010, 3, :o4, 1269136800
And I Is working NOW !!!!
Now I need to wait to the end of 2010 to see what our country decides
to do about time saving and repeat (or not) the comment for the lines:
tz.transition 2010, 10, :o5, 1287284400
tz.transition 2011, 3, :o4, 1300586400
Thanks a lot.

I have the same two lines in my file and yet on my system, 'Buenos Aires'
timezone is -3:00. I am beginning to suspect that on Linux, the system TZ
info is used. I'll dig into it some more.

The ActiveSupport::TimeZone['Buenos Aires'] object has the base offset (-3).
Finding out if Daylight Savings is in effect requires specifying a date.
You want the glory/frustration of reporting this bug?

You might try updating your tzinfo gem (if you have it installed it
takes precendence over the one bundled in rails) - new versions are
released every so often incorporating changes to the definition files
