Iterate over Ruby Time object with delta

Question

Is there a way to iterate over a Time range in Ruby, and set the delta?

Here is an idea of what I would like to do:

for hour in (start_time..end_time         


        

Answer 1

Range#step method is very slow in this case. Use begin..end while, as dolzenko posted here.

You can define a new method:

  def time_iterate(start_time, end_time, step, &block)
    begin
      yield(start_time)
    end while (start_time += step) <= end_time
  end

then,

start_time = Time.parse("2010/1/1")
end_time = Time.parse("2010/1/31")
time_iterate(start_time, end_time, 1.hour) do |t|
  puts t
end

if in rails.
