Keep it to yourself until you are ready to leave. There is no advantage to disclosing your plans too early. About 20 years ago, I made the mistake of telling a coworker about my outside contracting gigs. He told the "big boss" (VP) about it, because I was not responding the coworker's weekend calls. A few days later I get a talking to by the VP about my outside endeavors and am told to stop. Of course, this request was ignored, but it created some drama at the time.
