date関数のフォーマット・オプション「ｙ」とか「ｈ」とか（続き)
昨日の件ですが。
昨日は頭に血が上っていたので、冷静さを欠いておりましたが。。。あの後、更に血圧が上がるようなことを言われて逆に凹んでしまいました。
確かにフォーマット・オプション「ｇ」は忘れてたけどさ。。。そんなに突っ込まなくてもいいじゃない。そもそも下らないミスしてるのは誰よ？＿|￣|○
冷静に考えると、戻り値の結果を強制的に変えてしまうのは良くないので、変わりにワーニングを発生させるように変更してみました。
フォーマット・オプション「ｙ」は強制的にワーニングを発生。
フォーマット・オプション「ｇ」と「ｈ」に関しては「ａ」か「Ａ」が存在しないときにワーニングを発生（存在するときはワーニングは発生しない）。
