(ZTimestampFormat fromString: '2001/02/03') format: Date today.

That is why the formatter/parser was written in the first place ;-) It is modelled after a Go standard library (http://golang.org/src/pkg/time/format.go) and some Ruby library I can't remember the name of. I implemented this as a proof of concept to see if/how it could be done. > Regards! > Esteban A.
