Date formats

Here's a handy date related tip I just read when I was looking around for ways to make an RSS feed valid.

If you go to a command line and run script/console, then type ActiveSupport::CoreExtensions::Time::Conversions::DATE_FORMATS it displays a hash containing default date formatting which can be used with to_s() like this:

      xml.pubDate(article.created_at.to_s(:rfc822))


It's also possible to add additional formats to the end of application.rb:

      ActiveSupport::CoreExtensions::Time::Conversions::DATE_FORMATS.merge!(
        :default => "%m/%d/%Y",
        :date_time12 => "%m/%d/%Y %I:%M%p",
        :date_time24 => "%m/%d/%Y %H:%M"
      )

      My personal faves:

      :iso_8601_date_only => ‘%Y-%m-%d’,
      :iso_8601_time_only => ‘%H:%M:%S%z’
