I agree, it's good to add this.

The package-info already has a link to APPNOTE.TXT and also the Info-ZIP 
format. However it might be good to at least have ZipEntry.getTime's 
javadoc mention that the time may be coming from extra block. This would 
provide coverage for cases where they don't match.
