Недопустимый часовой пояс

Question

Просто интересно, почему это происходит:

1.9.3-p327 :001 > Time.now.zone 
=> "YEKT" 

1.9.3-p327 :002 > Time.now.in_time_zone("YEKT") 
ArgumentError: Invalid Timezone: YEKT 

YEKT - это временная зона моего города (Екатеринбург).

Что, черт возьми, происходит? Я настраиваю проект и пытаюсь исправить все тесты, но не могу исправить это поведение. Или я могу подражать другому текущему часовому поясу (без изменения кода в идеале)?

Answer 1

Почему это происходит (спасибо @Athar):

Time.now.zone возвращает часовой пояс системы, в то время как in_time_zone работает со строгим списком (ActiveSupport::TimeZone.all.collect(&:name))

Обход : Вы можете указать свой часовой пояс таким образом:

TZ=UTC rails console 

1.9.3-p327 :001 > Time.now.zone 
=> "UTC" 

«UTC» - действующий часовой пояс, поэтому все работает.

Answer 2

Это доступные временные интервалы.
