How do I create a custom method to convert unix timestamp to UTC?

Question

I'm using this quite a bit to convert Unix timestamps that I receive from a third-party API, into UTC datetimes:

Time.at(1386549840).utc.to_datetime

How can I create a custom method to keep from repeating that so much? I use this primarily in my models and some background job workers.

Something like:

1386549840.convert_to_utc

This happens to be in a Rails 4 app using Ruby 2.0, FWIW.

Answer 1

Write a method yourself to do it:

class Fixnum
  def convert_to_utc
    Time.at(self).utc.to_datetime
  end
end

Classes in Ruby are open for extension.
