Hello everyone! I have a question :) When I run this command : puts Time.now I got => 2009-02-18T14:31:17-08:00 But if then I do this : require 'date'; expiration_date = DateTime.new(2008, 02, 18, 12, 12, 13); puts expiration_date I got => 2008-02-18T12:12:13+00:00 My question is : What is the "-08:00" ? I assume it's the timezone? Then how to set my expiration_date variable to have the same timezone? Thank you!

DateTime.new is an alias for DateTime.civil. You can see its documentation here: http://www.ruby-doc.org/stdlib/libdoc/date/rdoc/cl... You're right that "-08:00" is something like a timezone. It's the offset from UTC (Coordinated Universal Time) and it's determined by your timezone. Anyway, as you can see in the documentation, there's an extra argument after the one for seconds where you can set your offset. It's set as a fraction of a day, so in your case you'd want to do something like this: expiration_date = DateTime.new(2008, 02, 18, 12, 12, 13, -8/24.0) HTH, Chris

Perfect! By the waym why -8/24.0 instead of -8/24 ? Thank you!

Nah: if you did -8/24 it would return -1 instead of -0.33~ That's because arithmethic operations always return a value as precise as the precisest one in the term, which in this case is an Integer, no floating point number.
