My last quick tip involved setting your time zone in Ubuntu Hardy, so now, how do you set your time zone in a Ruby on Rails application? Rails 2.1 makes it much easier to manage time zone settings than it was previously.
Add the following to your environment configuration file:
config.time_zone = 'Arizona'
Replace Arizona with your own time zone. You can find a list of valid values by running any of the following rake tasks:
rake time:zones:all rake time:zones:local rake time:zones:us
Your data will still be stored in UTC time, but it will be converted into the specified time zone when it is type cast on retrieval.
Update: If you set both your server's time zone and your applications time zone then you may see some incorrect times. I believe this is because you'll be storing local times and the Rails app will be trying to convert them to local – a double conversion. So be careful.
