How would i write this language in a parser in javaCC

7. Overwrite the .jj file with a grammar of your choosing. Your grammar should have at least 4 production rules. Test that your parser works for the defined language. EBNF GRAMMAR CHOSEN:

EBNF language chosen:

time = time-of-day zone

time-of-day = hour ":" minute [ ":" second ]

hour = 2DIGIT / obs-hour

minute = 2DIGIT / obs-minute

second = 2DIGIT / obs-second

zone = (FWS ( "+" / "-" ) 4DIGIT) / obs-zone
