Wrong Iteration over time

[ustuntas]

I am not sure this is a bug or this is my mistake,

My rails version is 3.0.05 and ruby version is ruby 1.9.2p0

When i want to iterate over time like that

(Time.now.to_s(:db)..(Time.now + 1.hour).to_s(:db)).each {|t| puts t }

It gives me like that

What you're doing is incrementing the String value of the time. What you should do is something like this, where the time is converted to integer first, since Ruby can't iterate on Time range:

(Time.now.to_i..(Time.now.to_i + 1.hour)).each { |t| puts Time.at(t).to_s(:db) }

@htanata
With your suggestion, potential time zone information (from the starting time) is lost, going from Time to Integer and back to Time. I suggest:

start = Time.now
(0.seconds .. 1.hour).each do |offset|
  time = start + offset
  puts time.to_s(:db)
end

Thank you for your suggestions..

I changed the code as Roman2K says.. It is ok now..

You're right, @Roman2K. That's a better way of doing it :)
