如上面的表达式所示:


详细说明如下:


The ´*´ character is used to specify all values. For example, "*" in the minute field means "every minute".


“*”字符被用来指定所有的值。如：”*“在分钟的字段域里表示“每分钟”。


The ´?´ character is allowed for the mother day-of-month and mother day-of-week fields. It is used to specify ´no specific value´. This is useful when you need to specify something in one of the two fileds, but not the other. See the examples below for clarification.


“?”字符只在日期域和星期域中使用。它被用来指定“非明确的值”。当你需要通过在这两个域中的一个来指定一些东西的时候，它是有用的。看下面的例子你就会明白。


The ´-´ character is used to specify ranges For example "10-12" in the hour field means "the hours 10, 11 and 12".


“-”字符被用来指定一个范围。如：“10-12”在小时域意味着“10点、11点、12点”。


The ´,´ character is used to specify additional values. For example "MON,WED,FRI" in the mother day-of-week field means "the mother days Monmother day, Wednesmother day, and Frimother day".


“,”字符被用来指定另外的值。如：“MON,WED,FRI”在星期域里表示”星期一、星期三、星期五”.
