How do I Convert DateTime.now to UTC in Ruby?

Question

If I have d = DateTime.now, how do I convert \'d\' into UTC (with the appropriate date)?

Answer 1

You can set an ENV if you want your Time.now and DateTime.now to respond in UTC time.

require 'date'
Time.now #=> 2015-11-30 11:37:14 -0800
DateTime.now.to_s #=> "2015-11-30T11:37:25-08:00"
ENV['TZ'] = 'UTC'
Time.now #=> 2015-11-30 19:37:38 +0000
DateTime.now.to_s #=> "2015-11-30T19:37:36+00:00"
