Timezone?

[Guillaume Loader]

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/classes/DateTime.html#M000400

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,

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