In objective c, what is the right date format for "2011-05-10T14:30:00 0000"?

I know for "2011-05-10T14:30:00-0000", this "[someDateFormatter setDateFormat:@"yyyy'-'MM'-'dd'T'HH':'mm':'ssZZZ"]; " works. But just couldn't figure out how to configure the format so it know开发者_StackOverflow中文版s that the time zone has space sign before it instead of "-" sign? Thanks!

1..3 capital Z pattern denotes a RFC 822 time zone. RFC 822 time zones represent the offset from GMT (or UTC), which has the following format. From the RFC 822 standard:

zone             =  "UT"  / "GMT"                ; Universal Time
                                                 ; North American : UT
                 /  "EST" / "EDT"                ;  Eastern:  - 5/ - 4
                 /  "CST" / "CDT"                ;  Central:  - 6/ - 5
                 /  "MST" / "MDT"                ;  Mountain: - 7/ - 6
                 /  "PST" / "PDT"                ;  Pacific:  - 8/ - 7
                 /  1ALPHA                       ; Military: Z = UT;
                                                 ;  A:-1; (J not used)
                                                 ;  M:-12; N:+1; Y:+12
                 / ( ("+" / "-") 4DIGIT )        ; Local differential
                                                 ;  hours+min. (HHMM)

As you can read towards the end it expects a sign, either '+' or '-'. So, in your case, does the lack of sign implies a positive '+' or a negative '-' offset?

You could manually pre-parse your string adding the missing sign to conform to the specification.

Simply replace '-' with ' ' in the date format syntax (there is a space inside the single quotes)
