Custom Timezone without DST

Hey guys

I’m having a few problems with the new TimeZone feature of Rails 2.1. Turns out that I am on “Brasilia” TimeZone, (UTC - 03:00), BUT my state is NOT on the daylight saving time. And there is no other timezone for my country with this offset from UTC (-3:00) and that does not use DST. So, I would like to do one of these two things:

  1. Create a custom time zone

OR

  1. Change “Brasilia” TimeZone to, on this specific app, not use the DST.

Is any of these options possible? Is there any other solution for the matter (like :use_dst => false, or something like that?)

Thanks,

Dante Regis
