If the date you’re trying to parse is already in your local time zone, it’s really … Read more
You lose nothing except a few kB of disk space by installing the Active Support gem. In your code, you require only the function you want: require ‘active_support/core_ext/hash/indifferent_access’ That way, you can be sure you are not getting anything else to mess up your namespace.

Or, when using in Ruby on Rails, you can configure what classes Rails should permit globally when … Read more
According to Date documentation: require ‘date’ Date.new(2001,2,25) #=> #<Date: 2001-02-25 Date.jd(2451966) #=> #<Date: 2001-02-25 Date.ordinal(2001,56) #=> #<Date: 2001-02-25 Date.commercial(2001,8,7) #=> #<Date: 2001-02-25 Date.parse(‘2001-02-25′) #=> #<Date: 2001-02-25 Date.strptime(’25-02-2001’, ‘%d-%m-%Y’) #=> #<Date: 2001-02-25 Time.new(2001,2,25).to_date #=> #<Date: 2001-02-25
You can use ActiveSupport’s TimeWithZone (Time.zone) object to create and parse dates in the time zone of your application: 1.9.3p0 :001 > Time.zone.now => Wed, 11 Jul 2012 19:47:03 PDT -07:00 1.9.3p0 :002 > Time.zone.parse(‘2012-07-11 21:00’) => Wed, 11 Jul 2012 21:00:00 PDT -07:00
ActiveSupport is more separate now in Rails 3. If you want the all active_support thing, you can require ‘active_support/all’ now. But if you want only the blank? method, you can try require ‘active_support/core_ext/string’

Edit: Note that I don’t necessarily interpret this change as meaning that all instances of memoize can or should be replaced w/ this pattern. … Read more
