Answer 1

これはactivesupportのバグ（これRailsのバグ）です。 activesupport-4.0.3/lib/active_support/values/time_zone.rbで

ライン282は

def parse(str, now=now) 
    # ... 
end 

そして同じファイルの行308で問題がルビーは後者nowがあるかどうかを理解するのに苦労デフォルトのparam now=now、である

def now 
    # ... 
end 

ですメソッド呼び出し、または単にローカル変数（param自体）です。

now=nowをnow=now()に変更すると、すべて正常です。

このバグはRails 4.0.6で修正されています。
