I have users entering in dates in a Ruby on Rails website. I parse the dates into a DateTime object with something like:
date = DateTime.new(params[:year].to_i, params[:month].to_i, params[:day].to_i, params[:hour].to_i, params[:minute].to_i) or
date = DateTime.parse(params[:date]) Both DateTimes will not be in the time zone of the user which I previously set with something like:
Time.zone = "Pacific Time (US & Canada)" How do I parse the above DateTimes to be in the right time zone? I know the DateTime.new method has a 7th argument for the time offset. Is there an easy way to look up the offset for a time zone in a given time? Or should I be using something other than DateTime?

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 do: Time. now + Time. zone_offset("PST") if you: require 'time' in your ruby script. guess, should have done that before commenting.
Configure your Rails app The most important one is the config. time_zone configuration in your config/application. rb file. ActiveRecord will help you convert from and to (which the documentation fails to explain) UTC and the time zone of your choice.
Ruby | DateTime parse() function DateTime#parse() : parse() is a DateTime class method which parses the given representation of date and time, and creates a DateTime object. Return: given representation of date and time, and creates a DateTime object.
Try:
Time.zone = "Pacific Time (US & Canada)" Time.zone.parse('8-11-2013 23:59:59') #=> Fri, 08 Nov 2013 23:59:59 PST -08:00 OR
Time.now.in_time_zone("Pacific Time (US & Canada)") OR
DateTime.now.in_time_zone("Pacific Time (US & Canada)") If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
