查找2 java.sql.Timestamps之间的小时或分钟差异？

Question

我将 Postgresql 数据库java.sql.Timestamp中的a 作为 Timestamp
数据类型存储，我想找出从数据库中存储的数据库到当前 timestamp
在数分钟或数小时内的差异。这样做的最好方法是什么？有内置的方法吗，还是我必须将其转换为long或其他形式？ __

我结束使用了此工具，只想将其发布给其他人（如果他们正在搜索）。

public static long compareTwoTimeStamps(java.sql.Timestamp currentTime, java.sql.Timestamp oldTime)
{
    long milliseconds1 = oldTime.getTime();
  long milliseconds2 = currentTime.getTime();

  long diff = milliseconds2 - milliseconds1;
  long diffSeconds = diff / 1000;
  long diffMinutes = diff / (60 * 1000);
  long diffHours = diff / (60 * 60 * 1000);
  long diffDays = diff / (24 * 60 * 60 * 1000);

    return diffMinutes;
}
