Rails: convert UTC DateTime to another time zone
time.in_time_zone(time_zone)
Example:
zone = ActiveSupport::TimeZone.new("Central Time (US & Canada)")Time.now.in_time_zone(zone)
or just
Time.now.in_time_zone("Central Time (US & Canada)")
You can find the names of the ActiveSupport time zones by doing:
ActiveSupport::TimeZone.all.map(&:name)# or for just USActiveSupport::TimeZone.us_zones.map(&:name)
if Time.zone
it's your desired time zone then you can use @date.to_time.to_datetime
> @date=> Tue, 02 Sep 2014 23:59:59 +0000> @date.class=> DateTime> @date.to_time=> 2014-09-02 12:59:59 -1100> @date.to_time.to_datetime=> Tue, 02 Sep 2014 12:59:59 -1100
In plain ruby, with only require 'date'
, use the new_offset
method:
require 'date'd=DateTime.parse('2000-01-01 12:00 +0200')l=d.new_offset('-0700')u=l.new_offset('UTC')puts "#{u.strftime('%a %F %T %Z')} ❖ #{l.strftime('%a %F %T %Z')}"
Tested with ruby 2.3.7 that came standard on Mac OS X 10.13.
