If you do need to add or remove time, it's a simple math thing (date +/- ((3*60) + 30).minutes). But you're looking to rewrite time zone behavior that already exists, and you shouldn't need to do this. For more information, I'd recommend you look at the documentation here: https://api.rubyonrails.org/v6.0.2.1/classes/ActiveSupport/TimeWithZone.html

Let’s say you want to advance one hour; all you have to do is add 3600 seconds to the date. time = Time.now #=> 2015-12-08 10:26:40 -0200 time + 3600 #=> 2015-12-08 11:26:40 -0200. Most calculations are easy to implement, but things get complex when you have to consider time zones.

You can either have date or datetime according to the documentation. Therefore: rails g model Item name:string desc:string date:datetime. or. rails g model Item name:string desc:string date:date. But the best practice is to use DateTime as a general purpose representation of time.

Time class has some limits. Firstly, it can only represent dates between 1970 and 2038 ( since Ruby v1.9.2, it can represent date from 1823-11-12 to 2116-02-20 ). Secondly, the time zone is limited to UTC and the system’s local time zone in ENV['TZ']. Rails provide a really good time class called ActiveSupport::TimeWithZone.

Returns a new DateTime where one or more of the elements have been changed according to the options parameter. The time options (:hour, :min, :sec) reset cascadingly, so if only the hour is passed, then minute and sec is set to 0. If the hour and minute is passed, then sec is set to 0.

You can do time math with these & get things like tomorrow’s date: Time.now + 1.day Other Rails-exclusive time methods: date = Time.current date.change(hour: 20) date.at_beginning_of_day And for formatting: date = Date.today date.to_formatted_s(:short) # "16 Jul" date.to_formatted_s(:long) # "July 16, 2018"
