hi,   I need to construct anew time object with hour->7,min-55,sec-33. Then how could i do it?. As i search for it, I found no constructor to make time object like this. Anybody?

Thanks, -Sadeesh kumar.

Take a look at the ActiveSupport::CoreExtensions::DateTime::Calculations#change method. There's no Time.new(args) method, but I think that'll get you what you're looking for.

HTH, Bill

Also, I’m not sure what Sadeesh meant by a time object with hour->7, min-55, sec-33.

The ruby Time class is really a point in time, so it represents, say 4:06 pm on July 10, 2008, rather than 16 hours and 6 minutes.

Rails provides an ActiveSupport::Duration class which does represent time intervals, they are created using methods on integers so you can do:

7.hours + 66.minutes + 33.seconds

And you can add or subtract a duration to/from a time so;

Time.now + 7.hours + 66.minuts + 33.seconds

Hi Bill Walton,    Thanks for your reply. But i am still struggling to use the ActiveSupport::CoreExtensions::DateTime::Calculations#change. Can you give me an example?

What have you tried? What were the results and how did they confuse you?

Best regards, Bill

Bill, require 'activesupport' print ActiveSupport::CoreExtensions::Time::Calculations::change(13) print ActiveSupport::CoreExtensions::Time::Calculations.change(13)

Well my problem is, I don't know how to use change method.

Thanks, -Sadeesh kumar.

Wow. Sorry about that. Check the documentation for the change method (bottom left frame) in ActiveSupport::CoreExtensions::Time::Calculations at api.rubyonrails.org. If it's not obvious how to use it at that point, try it out in irb. When you have some concrete 'tried this, got that, don't understand why' type results, come back.

Best regards, Bill
