查找2 java.sql.Timestamps之间的小时或分钟差异？

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;}
