例外
例外解説
System.ArgumentOutOfRangeException値が負の数か、 ゼロ（0）より小さいときに発生します。
解説

PrimaryInterval に生成されたサイクルほうが表示されるアクティビティの期間より比較的長い場合は、短い期間のアクティビティを非表示にしたほうがいいことがあります。MinimumActivityDuration プロパティによって可能になります。たとえば、プロパティを 30 分の値に設定する場合は、30 分より短い期間の予定を表示せず、30 分より長い期間の予定を表示するためにもっとの利用可能スペースを提供します。

注: 指定値の Seconds および Milliseconds コンポーネントは割り当てのときにストリップ アウトされます。UltraTimelineView は、1 分以下の時間ユニットを認識しません。
