java 格式匹配_java中时间格式匹配

// This file contains date formats that Frink will parse.

// See documentation for SimpleDateParser or docs/index.html for more details.

//

// Now that regular expressions are possible in Frink, I'd like to replace this

// whole mess with a regexp-based solution, which would be more flexible and

// more powerful.

// Symbol Meaning Presentation Example

// G era designator Text AD

// y year Number 1996

// M month in year Text & Number July & 07

// d day in month Number 10

// Most significant digits are first, as it should be. These are the

// preferred formats. This also matches ISO-8601 date conventions, so if

// you're trying to be international, always use yyyy-MM-dd.

// You can also define the default output format with 4 pound signs.

// Without any definition, you get the Java default (which should theoretically

// get it from your system's settings,) but the following gives lots of

// information:

#### G yyyy-MM-dd hh:mm:ss.SSS a (E) zzzz ####

// Make it so we can parse the default output format.

### G yyyy-MM-dd hh:mm:ss.SSS a (E) zzzz ###
