Using java.time

    // Midnight (local time), 23 September 2017
    ZonedDateTime.of(2017, 09, 23, 13, 0, 0, ZoneId.systemDefault()).toInstant()
);

Using Cron

CalendarExecutorService executor = CalendarExecutorService.threadPool();

CronParser parser = new CronParser(CronDefinitionBuilder.instanceDefinitionFor(CronType.QUARTZ));

executor.schedule(
    () -> System.out.println("Ding dong."),
    // Every hour, on the hour, Monday to Friday, 9am to 5pm
    parser.parse("0 0 9-17 * * * 1-5")
