From http://docs.oracle.com/javase/7/docs/api/java/util/Calendar.html#HOUR:
从http://docs.oracle.com/javase/7/docs/api/java/util/Calendar.html#HOUR：
Calendar.HOUR = Field number for get and set indicating the hour of the morning or afternoon. HOUR is used for the 12-hour clock. E.g., at 10:04:15.250 PM the HOUR is 10.
Calendar.HOUR_OF_DAY = Field number for get and set indicating the hour of the day. HOUR_OF_DAY is used for the 24-hour clock. E.g., at 10:04:15.250 PM the HOUR_OF_DAY is 22.
Calendar.HOUR = get 和 set 的字段编号，指示上午或下午的小时数。HOUR 用于 12 小时制。例如，在 10:04:15.250 PM，HOUR 是 10。
Calendar.HOUR_OF_DAY = 用于获取和设置指示一天中的小时的字段编号。HOUR_OF_DAY 用于 24 小时制。例如，在晚上 10:04:15.250，HOUR_OF_DAY 是 22。
