i have date range 

(DateTime.now.change({hour: 01}).to_datetime.to_i .. DateTime.tomorrow.change({hour: 23}).to_datetime.to_i).step(1.hour) do |date|

Its because Time.at uses timezone what is +3h in your country http://api.rubyonrails.org/classes/Time.html#method-c-at_with_coercion

I think what you need is beginning_of_day and end_of_day

(Date.today.beginning_of_day.change(hour: 01).to_i..Date.today.end_of_day.to_i).step(1.hour) do |date|
  p Time.at(date)
end

This will return you
