Available in: v3.0.20 v3.1.12 v3.2.22.5 v4.0.13 v4.1.16 v4.2.9 v5.2.8.1 v6.0.6 v6.1.7.10 v7.0.10 v7.1.6 v7.2.3 v8.0.4 v8.1.2

Compare with:

self.use_zone(time_zone)

Allows override of Time.zone locally inside supplied block; resets Time.zone to existing value when done.

class ApplicationController < ActionController::Base
  around_action :set_time_zone

  private
    def set_time_zone
      Time.use_zone(current_user.timezone) { yield }
    end
end

NOTE: This won’t affect any ActiveSupport::TimeWithZone objects that have already been created, e.g. any model timestamp attributes that have been read before the block will remain in the application’s default timezone.

Parameters

time_zone req
