Get UTC offset in Ruby

I'm trying to get the UTC offset for a datetime. The datetime is saved as:

Fri, 31 May 2013 15:19:08 EDT -04:00

What I'd like to get is "-04:00". When I do object.utc_offset, I get -14400. What function should I use?

You are looking for strftime:

Time.now.strftime("%:z")

That will give you the offset such as "-04:00".

vgoff and Matt Johnson beat me to it, but for further elaboration see page 717-720 and table 27.18 in Programming Ruby 3rd Edition (The Pickaxe book), for further elaboration. %z gives hour offsets, %Z gives the time zone name, e.g. MDT, PST, etc.

Its in seconds. Divide by 3600 for hours, or 60 for minutes.

But if you want the formatted offset string, use vgoff's answer.
