I need to generate an HTTP (GMT) date string in Ruby. This is because of a requirement of an API that I'm consuming.
What is an easy (out of the box) way to generate it?

I found that Ruby comes with a method for the Time class out of the box for this:
Time.now.httpdate # => "Thu, 06 Oct 2011 02:26:12 GMT"
The time class also supports the following methods
Time.now.iso8601 # => "2011-10-05T22:26:12-04:00"
Time.now.rfc2822 # => "Wed, 05 Oct 2011 22:26:12 -0400"

Worth mentioning that this didn't work for me on Ruby 2.6.5p114 unless I `require "time"` explicitly. – jordelver Mar 03 '20 at 14:00

does Time.now.getgm work for you?
Time.now.gmt? #=> fale
Time.now.getgm.gmt? #=> true

1Thanks. But it doesn't, I needed the GMT string as "Thu, 06 Oct 2011 02:26:12 GMT" and what the "getgm" method returns is a Time not a string. "Time.now.httpdate" did the job. – Tonatiuh Mar 31 '17 at 23:33
