日期比较和操作功能？ [英] Date Comparison and Manipulation Functions?
问题描述
是否有一些日期和时间比较功能可以比较，比如说
是否比2002年9月22日晚10/05/05？ （或02/09/22格式，yy / mm / dd）
02/11/07与02/11/07相同吗？
是22:02:51之后的14:05:18？ （24小时一天很好）
02/28/04之后的日期是02/29/04，或者是09/30/08之后的日期
10/01/08？
03/03/03 20:10:08 03/04/03 14:00:00之后怎么样？可能其他人
就足够了。

Are there some date and time comparison functions that would compare, say,
Is 10/05/05 later than 09/22/02? (or 02/09/22 format, yy/mm/dd)
Is 02/11/07 the same as 02/11/07?
Is 14:05:18 after 22:02:51? (24 hour day is fine)
How about the date after 02/28/04 is 02/29/04, or the date after 09/30/08 is
10/01/08?
How about is 03/03/04 20:10:08 after 03/07/03 14:00:00? Probably the others
above will suffice.
