[CoffeeScript]TwitterAPIのcreated_atからDateオブジェクトを返す関数

More than 5 years have passed since last update.

    newDate_from_tweetCreatedAt = (created_at)->

created_at = created_at.split ' '
# 投稿日時変換 "Mon Dec 01 14:24:26 +0000 2008" -> "Dec 01, 2008 14:24:26"
post_date = created_at[1] + " " + created_at[2] + ", " + created_at[5] + " " + created_at[3]
# 日時データ処理
date = new Date post_date # 日付文字列 -> オブジェクト変換
date.setHours(date.getHours() + 9) # UTC -> JST (+9時間)
return date
