このアプリは、「年、月、日、時間、分、秒」のいずかの入力に対して、対応する「年、月、日、時間、分、秒」を一括計算し、一括表示する時間計算専用電卓です。 電気回路や機械を扱っていると、「この部品の寿命は、平均60,000時間です」などと説明されますが、「60,000時間って、何日?、何年?」となることがあります。この時間計算用電卓を使うと、一発で「年、月、日、時間、分、秒」に変換表示されるので便利です。(60,000時間は、2500日、6.85年です) 入力した2つの日時の差分を計算する機能を追加しました。業務時間の計算の際などに利用できます。 表示する「年、月、日、時間、分、秒」は、小数点以下2桁までです。 入力する「年、月、日、時間、分、秒」は、この限りではありません。 尚、起動時直後は、1年に対する「年、月、日、時間、分、秒」が表示されています。 また、1ヶ月は30.41666667日、1年は365日として計算しており、うるう年は加味していませんので、その点はご考慮ください。 誤って、ソフトキーボード を立ち上げてしまった場合は、「Enterキー」又は、「改行キー」を押してください。
