Class Method Details

._instance(specification, options = {}) ⇒ When::TM::TemporalPosition, ...

Note:

options の中身は本メソッドによって更新されることがある。

Note:

:tz は ‘Asia/Tokyo’など時間帯を表す文字列をキーにして、登録済みのWhen::V::Timezone, When::Parts::Timezoneを検索して使用する。 :clock はWhen::Parts::Timezone::Baseオブジェクトをそのまま使用するか ‘+09:00’などの文字列をWhen::TM::Clock化して使用する。 :tz の方が :clock よりも優先される。
