プログラムにおける分に変換する「タイムトラベル」

Question

私は現在の時刻をユーザーに尋ねることになっている「タイムトラベル」プログラムを書いています、彼らの目標走行時間、それらの値を中継するための2つの時刻の差を計算します関数を使用し、時間差が大きすぎる場合は時間の移動を許可しないか、または許可されている場合は、将来または過去の場合に印刷します。今の私の問題は、ジャンプが発生した後、プログラムの最初の反復または最初のジャンプが関連していると考えられる現在の時刻が更新されておらず、プログラムが目標時刻の代わりにデフォルトになることですこれはジャンプが発生した後の技術的な "現在の時間"であるはずです。私はこれを数時間試してみることができませんでした。だから誰かが私を助けてくれることを願っています。

は、あなたの代わりに「現在の時間」のためにユーザーの入力を得るための、システム時刻コールを使用していないのはなぜ

お時間をいただき、ありがとうございますか！また、12時間ではなく24時間制を使用し、プロセス内でam/pmを満たす必要がなくなりました。

AMヨーロッパ、ロシア、オーストラリア、または米国北部のドライブを除いて、c_hrs * 60は（少なくとも）60時間（最大でも）24 * 60です。過度の時間の録音です。時間（c_mins * 60）の代わりに分（MINUTES）を参照するつもりはありませんか？
