Time Regex in Cocoa

Question

I need some help to write a reg exp to find times in the following format 00:00 and 0:00 (up to max value 23:59)

NSPredicate *timePredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES ??"];
NSArray *filteredArray = [someArray filteredArrayUsingPredicate:timePredicate];

The array looks like this. "3465,11:55,13:01,2311,122,4:34", "3466,15:10,1233,13:11,6:56", — Anders Öhrn, Mar 31 '11 at 16:46

This should work in ICU regex, the syntax used in NSPredicate

\b(2[0-3]|[01]?\d):[0-5]\d\b

It looks for a word boundary \b followed by either 20-23, 00-19 or 0-9, then comes colon and finally 00-59 before another word boundary.

The word boundaries are important, since they prohibit matches of e.g. 123:456.
