If this value is not supplied, the value from a call to the getDate method is used. JavaScript の Date オブジェクトは、単一の瞬間の時刻をプラットフォームに依存しない形式で表します。 Date オブジェクトは協定世界時 (UTC) の1970年1月1日からの経過ミリ秒数を表現する Number 含んでいます。, JavaScript の日時は、基本的に協定世界時 (UTC) の1970年1月1日深夜0時からの経過ミリ秒数で指定されます。この日付と時刻は、コンピューターに記録される日付と時刻の値の主な基準値である UNIX Epoch と同じです。, 注: Date オブジェクトの中心となる時間値は UTC ですが、日付と時刻、またはその一部を取得する基本的なメソッドは、すべて地方時 (ホストシステムなど) のタイムゾーンとオフセットで動作することを覚えておくことが重要です。, Date の最大値は、確実な整数の最大値 (Number.MAX_SAFE_INTEGER、9,007,199,254,740,991) と同じ値ではないことに注意が必要です。代わりに ECMA-262 では、 UTC の 1970年1月1日から前後 ±100,000,000 (1億) 日 (つまり、紀元前271821年4月20日 - 紀元275760年9月13日) を標準の Date オブジェクトで表すことができると定義しています。, 様々な形式で日時を取得したり、タイムゾーンの変換を行ったりすることができる方法はたくさんあります。特に便利なのは、世界時標準 (World Time Standard) で定義されている世界標準時である協定世界時 (UTC) で日付と時刻を出力する関数です。 (この時間は歴史的にグリニッジ標準時として知られており、 UTC はイギリスのロンドンとその近くのグリニッジを含む子午線に沿って位置しています。) ユーザーの端末は現地時間を提供します。, 地方時の日付と時刻の個々の部分を読み書きするメソッド (getDay() や setHours() など) に加えて、 UTC を使用して日付と時刻を読み書きする同等のメソッド (getUTCDay() や setUTCHours() など) もあります。, 注: ブラウザーごとに動作が異なり一貫性がないため、 Date.parse で文字列を解釈しないように強くすすめます。, 注: Date コンストラクター (または同等の Date.parse) で日付文字列を解釈することは、ブラウザーごとに動作が異なり一貫性がないため、避けるように強くすすめます。, 西暦 0 年から 99 年までの間の年を生成および取得するには、Date.prototype.setFullYear() メソッドと Date.prototype.getFullYear() メソッドを使用してください。, 以下の例で、2 つの JavaScript の日付の間で経過した時間を計る方法を示します。, 日 (サマータイム切り替えによる)、月、年の長さが異なるため、経過時間を時、分、秒以上の単位で表現するには、いくつかの問題に対処する必要がありますので、事前によく調べて使用してください。, 注: Web Performance API の高精度時刻機能に対応しているブラウザーでは、 Performance.now() で、 Date.now() よりも高信頼かつ高精度な経過時間の測定が可能です。, この場合、整数だけを返すことが重要です (単純な除算ではできません)。また、実際に経過した秒数を返すことも重要です (ですから、上の例では Math.round() ではなく Math.floor() を使っています)。, Last modified: Nov 4, 2020, by MDN contributors. */, /** Get Current Date & Time in JavaScript Use Date () function to create an object in JavaScript with current date and time. */, /** Gets the hours in a date, using local time.
