From c9c5788a527b70d7f983e2b4b47e3afd863d9f48 Mon Sep 17 00:00:00 2001 From: Andrew White Date: Sat, 23 Apr 2016 14:46:50 +0100 Subject: Add compatibility for Ruby 2.4 `to_time` changes In Ruby 2.4 the `to_time` method for both `DateTime` and `Time` will preserve the timezone of the receiver when converting to an instance of `Time`. Since Rails 5.0 will support Ruby 2.2, 2.3 and later we need to introduce a compatibility layer so that apps that upgrade do not break. New apps will have a config initializer file that defaults to match the new Ruby 2.4 behavior going forward.
