I have set the time zone in /config/application.rb, and I expect all times generated in my app to be in this time zone by default, yet when I create a new DateTime object (using .new), it creates it in GMT. How can I get it to be in my app's time zone?
/config/application.rb
config.time_zone = 'Pacific Time (US & Canada)' irb
irb> DateTime.now => Wed, 11 Jul 2012 19:04:56 -0700 irb> mydate = DateTime.new(2012, 07, 11, 20, 10, 0) => Wed, 11 Jul 2012 20:10:00 +0000 # GMT, but I want PDT Using in_time_zone doesn't work because that just converts the GMT time to PDT time, which is the wrong time:
irb> mydate.in_time_zone('Pacific Time (US & Canada)') => Wed, 11 Jul 2012 13:10:00 PDT -07:00 # wrong time (I want 20:10)

Timezone aware object using datetime now(). time() function of datetime module. Then we will replace the value of the timezone in the tzinfo class of the object using the replace() function. After that convert the date value into ISO 8601 format using the isoformat() method.
A DateTime object is created with DateTime::new , DateTime::jd , DateTime::ordinal , DateTime::commercial , DateTime::parse , DateTime::strptime , DateTime::now , Time#to_datetime , etc. require 'date' DateTime. new(2001,2,3,4,5,6) #=> #<DateTime: 2001-02-03T04:05:06+00:00 ...>
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 Another way without string parsing:
irb> Time.zone.local(2012, 7, 11, 21) => Wed, 07 Nov 2012 21:00:00 PDT -07:00 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
